What does intervention involve in a service setting?

Intervention in a service setting is primarily focused on ensuring the safety and well-being of patrons, especially when it comes to responsible alcohol service. This often involves recognizing signs of intoxication and taking appropriate action to prevent further alcohol consumption that could lead to harm for the individual or others. Discontinuing service to an intoxicated patron is a critical aspect of responsible service practices. It demonstrates an understanding of one's duty of care and safeguards against potential alcohol-related issues, such as accidents or disturbances.

In contrast, the other choices promote behaviors and practices that could contribute to further intoxication or unwise consumption of alcohol, which is contrary to the principles of responsible service. Encouraging intoxicated guests to stay longer or offering unlimited drink specials could exacerbate their condition and lead to negative consequences, while discussing policies with sober guests, while important for setting expectations, does not directly address the immediate needs of an intoxicated patron.
