Who Preston is
An operator first. An expert witness because of it.
Preston Rideout has worked in bars, nightclubs, restaurants, and hotels since 1996: bartender, bar manager, nightclub general manager, and director of bar operations for multi-unit groups. Since 2010 he has run Rideout Hospitality Consulting, advising operators across the United States, Mexico, and the Bahamas on alcohol service, training, and venue operations. He is retained by counsel to explain how a venue was actually run, and how that compares with recognized industry practice.
Areas of expertise
Where his experience applies
Alcohol Service & Overservice
Service sequence, drink counts, tab records, pacing, bartender observations, and the intervention steps a trained server is expected to take.
Overservice analysisBar & Nightclub Operations
Staffing, door procedures, capacity, patron management, closing routines, incident response, and the management controls that hold them together.
Bar and nightclub expert witnessRestaurant & Hospitality Operations
Restaurant, hotel, resort, and casino alcohol programs; how beverage service is supervised in settings where it is one part of a larger operation.
Restaurant and hospitality expert witnessResponsible Alcohol Service

Responsible service standardsPremises & Security at Hospitality Venues
Operational premises and security issues at bars, nightclubs, restaurants, and hotels: staffing, crowd management, and incident handling, within hospitality operations.
Hospitality premises liabilityOperational experience, applied to litigation
Written policies say how a venue should run. The records show how it did.
Preston spent two decades pouring drinks, closing bars, managing door staff, and running nightclubs before he was first retained as an expert. That experience is what he brings to a case file: he reads a point-of-sale report, a staffing schedule, or a surveillance clip the way a manager on shift would, and explains to counsel, and to a jury, what a trained bartender or manager should have recognized and done.
He holds 112 seller-server and responsible-vendor certifications across 48 states and the District of Columbia, co-authored a bartender training manual, and has consulted for hotels, restaurant groups, casinos, and nightclubs. When a case turns on what a bartender in Texas, Florida, or Illinois was trained to recognize, Preston is not describing that training from the outside: he has completed the same state course and can tell a jury exactly what it does and does not teach. Those are the standards he applies, and he applies them the same way for plaintiffs and for defendants.
The difference between the written program and the actual practice is usually where the case is decided.
