What is the legal limit for serving alcohol to one person at a time?

The legal limit for serving alcohol to one person at a time is set to prevent overconsumption and maintain responsible serving practices. In Arizona, the limit specifically defines that a single person can be served no more than 50 ounces of beer at one time. This regulation is important as it helps to promote safe drinking habits and minimizes the risk of alcohol-related incidents.

Other options, such as serving any amount, only water, or unlimited quantities, do not align with Arizona's responsible service laws. Serving any amount would ignore the necessary limits designed to protect patrons. Offering only water disregards the context of the question, which pertains to serving alcoholic beverages. Similarly, allowing unlimited quantities would pose significant health and safety risks and contradict the spirit of responsible consumption laws in the state.
