What should a server do if they witness a co-worker breaking the rules?

When witnessing a co-worker breaking the rules, reporting the action to a manager while following the correct chain of command is the most appropriate course of action. This approach ensures that the situation is handled professionally and effectively. It maintains a respectful workplace environment by not escalating the issue in front of customers or other staff members, which could lead to unnecessary conflict and a negative experience for guests. By involving management, the server ensures that the situation is assessed and addressed appropriately according to the establishment's policies and procedures. This not only promotes accountability among staff but also aligns with the operational standards of the diner, fostering a better work environment for everyone.
