What action should be taken 15 minutes after closing?

Taking the action of locking all doors 15 minutes after closing is essential for ensuring the security and safety of the restaurant. This measure protects the premises from unauthorized access and ensures that no customers or staff members are present after hours, helping to prevent potential theft or vandalism.

Ensuring that all entrances are secured provides peace of mind for the staff working late and is an important protocol in maintaining the establishment's integrity. While other actions, such as performing the final close to print reports, cleaning the lobby, and verifying safe funds, are also important tasks that need to be carried out at closing time, locking the doors should be prioritized to secure the space before focusing on administrative and maintenance tasks.
