Mandatory Training Increases Drink Refusals to Intoxicated Patrons in California
Klein Buendel scientists and staff are collaborators on a study that evaluated mandatory responsible beverage service training in California and its association with higher refusals of service to apparently intoxicated patrons in drinking establishments. The study, led by Dr. Robert Saltz at the Pacific Institute for Research and Evaluation, has been published in the Journal of Studies on Alcohol and Drugs.
The California Responsible Beverage Service (RBS) Training Act mandated training for all alcohol servers by 2023, giving this multi-institutional research team a rare opportunity to see how a statewide initiative might influence server behavior.
In 2022, 300 licensed on-premises establishments were sampled in nine counties in and around the San Francisco Bay Area. From July 2022 to January 2023, pseudo-patron and observer teams visited each establishment, and pseudo-patrons attempted to buy alcohol while displaying obvious signs of intoxication. The outcome of each purchase attempt and characteristics of establishments, servers, and pseudo-patrons, and month, day, and time, were recorded. In 2024, the same premises were visited as a follow up.
At baseline, 19.6% of the outlets refused service to the pseudo-patron. At follow up, the refusal rate increased significantly to 39.2% in a regression model controlling for establishment, server, and pseudo-patron characteristics. A typology of establishments (such as sports bar, casual restaurant, fine dining restaurant) did not show any association with refusal rate except that fine dining places refused more often than other types of establishments. Observers’ ratings of how obvious the pseudo-patron’s apparent intoxication was strongly associated with refusals.
The researchers conclude that there was substantial improvement in alcohol over-service refusals two years after the California mandatory RBS training law went into effect.
