Which of the following is a reasonable effort to avoid serving intoxicated customers?

Offering food and snacks for purchase at all times is a reasonable effort to avoid serving intoxicated customers because food can help to slow the absorption of alcohol in the body. When patrons consume food alongside alcoholic beverages, it can mitigate some of the acute effects of alcohol, allowing for a more responsible drinking experience. This practice encourages a balanced approach to consumption, reducing the likelihood of intoxication and promoting a safer environment for both customers and staff.

In contrast, other options do not effectively address the issue of serving intoxicated customers. For instance, offering more alcoholic beverages would likely lead to increased consumption, which could exacerbate intoxication. Allowing customers to pour their own drinks may result in over-serving themselves, as many individuals might not accurately gauge their own limits. Discouraging the use of alternative transportation could lead to unsafe situations for those who have consumed too much alcohol, risking both their safety and that of others in the community.
