Which of the following is NOT a technique for promoting responsible drinking?

Encouraging guests to play drinking games is not a technique for promoting responsible drinking. Drinking games typically involve competition and often lead to consuming alcohol quickly or in larger quantities, which can encourage irresponsible drinking behaviors and lead to intoxication. Such activities can undermine efforts to create a safe environment for alcohol consumption.

In contrast, offering free food with drinks, providing water service alongside alcohol, and suggesting low-alcohol options are recognized techniques for promoting responsible drinking. These methods help to slow down the consumption of alcohol, provide hydration, and present alternatives that allow individuals to enjoy social situations with lower risks associated with drinking.
