What action should a bartender take upon noticing a customer displaying disorderly behavior?

When a bartender observes a customer exhibiting disorderly behavior, documenting the behavior in an incident log is essential for several reasons. This action serves as an official record of the incident, which can be crucial for future reference and liability protection. An incident log can help establish a pattern of behavior if the situation escalates or if the customer returns in the future. Proper documentation also demonstrates that the bartender is taking the situation seriously, which can be beneficial for both the establishment and the safety of other patrons.

In addition, maintaining an accurate record of such incidents can support any required actions taken later, like discussing the behavior with management or addressing it with the individual involved, ensuring that accountability is upheld. This practice also aligns with responsible alcohol service principles, promoting a safe environment for everyone in the venue.
