"I listen to customer requests and keep track of customer information when they make a reservation. I communicate to the waitstaff any special requests to make sure the customer is happy."

Your interaction with the customers will primarily be on the phone when they are calling for reservations and when you greet them at the door. When customers make requests beyond your capacity, you have the entire waitstaff to support you. Let them know you work as a team and communicate with the waitstaff to ensure the customer is taken care of.
