Final answer:
Recording the fight in an incident log is important for legal purposes and to address security risks.
Step-by-step explanation:
If Kyle starts a fight in your bar/restaurant, it is important to record the incident in an incident log. This log serves as a record of any issues or altercations that occur on your premises. It can be useful for legal purposes, such as providing evidence in case any legal action is taken against the establishment. Additionally, having an incident log helps to establish a pattern of behavior and can assist in identifying and addressing potential security risks.
