Final answer:
When confronted with a panhandler outside a grocery store, it is best to ask them to panhandle in a designated spot away from doors and moving vehicles.
Step-by-step explanation:
When confronted with a customer complaint about someone panhandling outside the grocery store, it is important to handle the situation in a responsible and respectful manner. The appropriate course of action would be to ask the man to panhandle in a designated spot in the parking lot, away from the doors and out of the path of moving vehicles. This ensures the safety of both the customers and the panhandler. Instructing the man to leave the premises may escalate the situation, and giving him money in exchange for leaving would not address the underlying concern.
