What is prohibited when it comes to serving alcohol in Nevada?

Serving alcohol while intoxicated is prohibited in Nevada because it poses a significant risk to public safety. Intoxicated servers may not be able to accurately check IDs, monitor patrons for signs of intoxication, or respond appropriately in the event of a critical situation. This rule is in place to ensure that servers maintain professional responsibility and to prevent further escalation of alcohol-related issues in a social setting. Practicing safe serving techniques is crucial for both the server's well-being and that of the patrons they serve.

The other options mention scenarios that do not reflect actual laws or regulations regarding alcohol service in Nevada. For instance, serving alcohol during holidays is allowed, and there are no restrictions on serving alcohol only in bars. Additionally, while there may be specific operational hours for various establishments, the law does not universally prohibit service after midnight across all venues.
