Final answer:
An incident log or establishment-specific documentation should note when alternative transportation is arranged for an intoxicated guest, including details of the intervention and transportation arrangements to protect guest welfare and reduce establishment liability.
Step-by-step explanation:
When alternative transportation has been arranged for an intoxicated guest, this must be noted on an incident log or similar documentation required by the establishment's policies. This log would typically include information such as the time the guest was identified as intoxicated, the actions taken by staff, details of the alternative transportation arranged, and any other relevant observations. This is important as it helps to ensure the welfare of the guest and reduce liability for the establishment.
