Keeping accurate records or notes about a serious refusal-of-service incident can help:

Documenting a serious incident — such as refusing service to an intoxicated customer or an altercation — by keeping accurate notes (per house policy) can help protect the server and establishment by showing that responsible steps were taken and the law was followed. If the incident later leads to a complaint, claim, or legal action, this record provides evidence of good-faith compliance. Many establishments have incident-report procedures for this reason. Understanding the value of documentation reinforces a careful, accountable approach to alcohol service.
