Information Silos: How They Harm All Stakeholders

RECAP OF PRIOR INSIGHT


  • Chronic alcohol-related problems, such as violence, DUIs, and neighborhood disruption are largely preventable by reducing overconsumption.


  • There are three proactive steps cities can take to effectively change the behavior of existing businesses, especially those with long-standing bad habits.


Step 1: Prepare to meet with the business. Obtain performance data and develop your written talking points.


Step 2: Meet with the business. Share performance data. Connect any issues to proven solutions. Emphasize the link between intoxication and calls for service. Review the ten “best practices to reduce overconsumption” in the Best Practices for Nightlife Establishmentsbooklet. Recommend and review cut-off logs to encourage accountability. Schedule a follow up in 30-45 days to review progress.


Step 3: Use Enhanced Bar Checks. They reinforce the city’s expectations, build trust, and strengthen partnerships. Where possible, reference case examples of enforcement to underscore accountability.


  • As improvements take hold, extend this 3-step process to other high-risk venues in the city.




Short on time? Skip to the recap below!



First, the real reasons that drunks aren’t cut off


Depending on which study you read, only 3% to 15.5% of customers who are identified as obviously intoxicated are cut off. Why so few? Usually, it’s not because the server wants more tips or the business wants more sales. The real reasons are systemic.


The law isn’t enforced. The Alcoholic Beverage Control rarely enforces the law against serving an obviously intoxicated person, §25602(a) of the Business & Professions Code. Imagine if traffic speed laws were never enforced. Chaos would follow. That’s the norm inside many late-night venues with excessive drinking.


Cut-offs are unpleasant. Refusing service can be awkward or confrontational. Few servers enjoy doing it. And if managers don’t require cut-offs, many servers tend to avoid them.


Lack of information and knowledge. Owners and managers often don’t realize how intoxicated customers drive up insurance premiums, deductibles, and customer churn (turnover). In the automobile insurance realm, studies show that higher insurance premiums motivate most drivers to improve. Likewise, if alcohol business owners understood how drunkenness affects their insurance costs, it could motivate them to operate more responsibly. Those who pay the insurance bill aren’t the ones making cut-off decisions.


Ethically, of course, staff should cut off intoxicated customers. But ethically, enforcement agencies should also enforce the law. Instead of finger-wagging, let’s solve the problem.



Internal information silos hinder learning in the business organization


Most alcohol businesses suffer from information silos, where critical information and knowledge are trapped in management layers, never reaching those staff members who need it.


For over a decade, I’ve led Advanced Bar Management workshops, in-person and, for my Johns Hopkins University clients, via Zoom.


A standard poll question that I ask participants is:


“How many years does an insurance claim stay on your record?”


Almost no one knows the answer: five years. And few people understand how multiple insurance claims can compound premiums and deductibles. I wasn’t surprised that my workshop attendees didn’t know this. After all, as a restaurant owner and general manager, I didn’t know, either. I only learned it after years of insurance claims made my insurance unaffordable.


That’s the journey many alcohol business owners take. Learning the hard way, if at all. 



External information silos lead to missed opportunities


The same void in information sharing exists beyond the business’s walls. Research that could inspire alcohol business operators to reduce the intoxication levels inside their business is never shared with them. Here are a few examples:


  • Overpouring Studies
    Research on the overpouring of spirits and wine shows its massive negative impact on sales and profit margins. In my Advanced Bar Management training, when business owners and managers learn about these findings, they often become eager to implement my “profitable pouring” practices. These actions reduce waste, improve profits, and lower intoxication levels inside establishments. The result is a more profitable business and a safer community.


  • The Biphasic Response (“The Pleasure Zone”)
    During my Advanced Bar Management training, participants are captivated when we explore the biphasic response to alcohol. That is, at first, alcohol produces pleasurable feelings, but over time, the effects become more depressant in nature.
    [1] Understanding the BAC level at which alcohol consumption shifts from pleasurable to negative and risky empowers both servers and customers. This new knowledge debunks the myth that “more is better,” and it affects attitudes and beliefs about drinking. Nearly every operator who learns this concept asks me for a complimentary Drinker Guide to display for guests. We’ll discuss the guide in a future Insight, but the key takeaway is simple. When customers understand the pleasure zone, that knowledge follows them out the door.




  • Studies on High-Intoxication Harms
    Decades of research demonstrate the steep rise in harm as intoxication increases. My Advanced Bar Management workshops are filled with these findings—studies I never encountered during my own years as a late-night club operator and that other hospitality professionals have never seen. These studies were buried in academic journals, far from the people who could benefit from them the most.


What do you think is more effective?

  • Telling servers to cut off drunk customers because too much alcohol consumption is unsafe. 

OR

  • Showing them the “relative crash risk”[1] chart that indicates a customer being cut off, whose BAC is .07, is twice as likely to get into a vehicle crash as a nondrinker. And if the customer is not cut off and their BAC rises to .15, the driver is now 22 times more likely to crash. 




Information sharing breaks silos


Stay tuned because our next two posts will discuss how sharing the Best Practices for Nightlife Establishments booklet with businesses shatters information silos and triggers critical change. When best practices replace legacy practices:


1.    Public safety is increased.

2.   City public safety expenses are reduced.

3.   Business profitability is improved.

RECAP


  • Customers are overserved alcohol and rarely cut off because:
  • The ABC doesn’t enforce the law against serving an obviously intoxicated person.
  • Staff who might enforce a cut-off policy are unaware of the rise in insurance costs due to claims involving drunk customers.
  • Staff aren’t exposed to the research that quantifies customer harm at higher BAC levels.


  • Business owners are unaware of many of the practices that can reduce high-risk intoxication inside their establishments.


  • The siloing of information between the research community and the hospitality industry harms all stakeholders. 


  • The broad sharing of information from research studies would provide business owners and managers with the knowledge, tools, and motivation to serve alcohol more responsibly.

That's the decision . . .
By Gregg Hanour • September 28, 2026
In our last blog we discussed how the overconsumption of alcohol is the enemy, not the moderate consumption of alcohol. Moderate Drinkers are Safer Multiple research studies have shown that people who consume alcohol and keep their BAC to below .06% are safer. “There is agreement in the scientific community about what defines ‘moderate drinking.’ Also, moderate drinking means limiting how fast you drink and, as a result, keeping your blood alcohol concentration (BAC) below .055.” (Source: Hester) In general, those who drink excessively are more aggressive and also get injured more seriously than those who drink moderately or not at all. Moderate drinkers do not appear to be at significantly higher risk of injury than nondrinkers. (Source: Scott and Dedel) The Higher the BAC, the Greater the Risk of Harm Alcohol follows a dose-response curve— higher BAC leads to higher risk across all major harms, including crashes, injuries, and violence. Harm rises exponentially as demonstrated by this chart from National Highway Traffic Safety Administration on the risk of crashing at given BAC levels.

The Root Cause: Overconsumption of Alcohol T he main purpose of CUP conditions for your on-sale alcohol businesses is to lessen any negative impacts and ensure the operation is in harmony with your community Most problems caused by your bars and restaurants are the direct result of the overconsumption of alcohol—including altercations, nuisance complaints from neighbors, and vehicle crashes. Cities that have calculated the net effect of alcohol businesses on their general fund have discovered a minimum net loss of $1 million dollars—caused mainly by calls for service due to violence and medical problems from overservice. The insurance industry says that 90% of insurance claims at bars and restaurants are the direct result of the overconsumption of alcohol. My experience as an operator and consultant to the hospitality industry suggest that 90% of the time, calls for service are due to one or more customers having consumed too much alcohol. Studies confirm the relationship between higher levels of intoxication and violence. Using Logic to Choose an Action to Solve the Problems Since the goal of writing conditions of approval is to lessen problem . . . And since most problems stem from the overconsumption of alcohol . . . Shouldn’t the conditions aim to lessen overconsumption? In fact, shouldn’t a major focus of your entire approval process—from approving, conditioning, and onboarding—be to message best practices to lessen overconsumption? In reducing the overconsumption of alcohol, all stakeholders benefit: Public safety is improved from less violence and fewer DUI tragedies. City public safety expenses are reduced. Business profits are protected from insurance claims and lawsuits. There are many ways planners and law enforcement can reduce overconsumption in newly-approved on-sale alcohol businesses. In reducing overconsumption, your city saves money—lots of money. This isn’t just our opinion. A Study to Bank On According to this study, for every $1 a city spends to reduce intoxication, it saves $260 (Levy & Miller)

Most city leaders assume their bars and restaurants pay for themselves. The numbers say otherwise—and closing the gap starts with rethinking two common assumptions.

I’ve been known to get a little obsessed with reaching goals — whether it’s catching a trophy brown trout over 10 pounds or hitting a Pick 6 for more than $50,000. Did I accomplish those goals? You’ll find out at the end. Another goal of mine is far more important and challenging: changing how California cities approve, condition, and onboard new on-sale alcohol businesses (restaurants, bars, clubs, and similar establishments). That's why I teamed with retired ABC District Administrator Lauren Tyson to design our upcoming workshop on best practices for conditional use permits (CUPs) and entertainment permits. The current process sucks. Yes, I sometimes use technical language. Who’s Behind This? I’ve spent years training hospitality operators, planners, and law enforcement on exactly this problem, and wrote a book on the topic, A Business Approach to Reducing DUI, along the way. Link to Gregg’s bio Lauren wrote the book on it — literally. As a former ABC District Administrator and author of Perils of Selling Alcohol: A Guide for Bar Owners Facing Legal Trouble, she’s seen exactly what puts ABC-licensed businesses at risk, and what actually protects them and the public. Link to Lauren’s bio How Do I Know the Current Process Isn’t Working? Let Me Count the Ways Personal experience. I went through the process twice — once in Costa Mesa and once in Irvine. In both cases, very smart, dedicated planners, working with law enforcement, created extensive conditions of approval. One business had 32 separate conditions. Both businesses followed every condition, yet both were still public nuisances for years. Working with applicants. Lauren and I have helped dozens of applicants successfully navigate their city’s CUP application process. Yet the operating conditions cities impose rarely (read never) have a meaningful impact on reducing violence or problems. Reviewing city policies statewide. We’ve collected CUP conditions and operating requirements from 35 cities across California, including several known for leading the way in responsible ordinance writing. The reality? A business can follow every specific condition of approval and still become a public nuisance. Training professionals. We’ve conducted in-person workshops for planners and law enforcement on this topic. Presenting at conferences. Together and separately, we’ve presented on these issues at professional conferences. Academic research. While writing my first book, A Business Approach to Reducing DUI, I researched the topic extensively, including contacting five of the leading urban planning universities to review their curriculum. Working directly with operators. I’ve trained over a thousand hospitality owners and managers. I understand their concerns, their daily realities, and why too many close. Revising how cities approve, condition, and onboard new businesses doesn’t just protect city resources and public safety — it also guides businesses toward practices that improve their profitability. The Bottom Line When cities use best practices to approve, condition, and onboard new on-sale alcohol businesses, the outcome looks very different. Applicants who complete the CUP process and open for business will hear consistent messaging — from planners, planning commissioners, code enforcement, and law enforcement — about the operational practices that significantly reduce violence and problems. Applicants will receive meaningful conditions of approval that, when followed, actually reduce risk for all stakeholders. Applicants will experience impactful communication with code enforcement and law enforcement that keeps the operator focused on practices that protect both the business and the community. That’s what effective onboarding looks like. We hope you’ll join us for our upcoming Zoom workshop. And if you twist my arm, I might even share a few brown trout fishing tips. Yes, I did catch that trophy brown — a 17-pound, 7-ounce beauty. I also hit that big Pick 6. If you ask how to hit a $50,000 Pick 6 at the racetrack, my advice is simple: Start with a $100,000 bankroll.

Alcohol Best Practices is pleased to announce a new Zoom workshop for public officials and law enforcement professionals involved in alcohol license oversight. Conditional Use Permits, Entertainment Permits, and On-Sale Alcohol Oversight 📅 Date: Wednesday, October 28, 2026 🕐 Time: 10:00 a.m. to 12:00 Noon,Pacific (2 Hours) 📍 Location: Live via Zoom (link emailed upon registration) ✅ POST Certification pending | APA Certified 2.0 CM COST -$330 per attendee -$990 flat rate per city (up to 10 attendees) Learn more Register for Workshop WHO SHOULD ATTEND This workshop is designed for professionals responsible for reviewing, approving, or monitoring alcohol licenses, including: • City planning officials • Law enforcement personnel • Code enforcement officers • Planning commissioners Everyone involved in approving, conditioning, or monitoring new ABC on-sale licensed businesses must deliver a consistent, informed message at every step of the process — this workshop ensures they can. WHY THIS WORKSHOP IS NEEDED After analyzing dozens of Conditional Use Permits (CUPs) from cities across California, we identified critical gaps in how cities handle new alcohol license approvals: Existing CUP processes lack essential messaging to applicants Legacy approval conditions miss the most impactful requirements Newly approved businesses receive little to no meaningful onboarding Until now, there has been no training resource for best practices in approving, conditioning, or monitoring new ABC on-sale licensed businesses. Contracting with us to revise your city's approval and onboarding process is a significant investment. This workshop offers a cost-effective alternative, equipping your team with proven strategies that: ✔ Reduce violence, DUIs and nuisance complaints ✔ Lower public safety expenses and calls for service ✔ Improve the profitability, performance, and professionalism of licensed businesses We look forward to seeing you there.
