When must a server check identification?

The scenario in which a server must check identification is primarily based on the laws governing alcohol sales. The correct choice emphasizes the server's responsibility to ensure that they are serving alcohol legally and ethically.

Checking the identification when a guest looks under 30 years old reflects the common practice of enforcing the age verification when there is any doubt. This age threshold can help protect the establishment from potential legal issues, as many jurisdictions set the legal drinking age at 21. By setting a slightly higher age threshold for verification, servers can err on the side of caution, ensuring compliance with the law and preventing underage drinking.

Other situations mentioned, such as checking ID when a guest looks under 21 or when they order multiple drinks, might also prompt a server to take a closer look. However, the specific choice of checking ID when a guest appears to be under 30 is a more protective measure and aligns with many establishments' policies to avoid any legal repercussions. The emphasis on the age of 30 encourages thoroughness in maintaining legal compliance, thereby safeguarding both the server and the establishment.
