What is "Expo Sweep" used for in the restaurant?

"Expo Sweep" refers to the procedure used to ensure that the restaurant's floor is kept clean and free of any debris or spills during busy service periods. This practice contributes to overall safety and hygiene in the dining area, as well as to the restaurant's presentation. Floor cleanliness is vital in maintaining a positive dining experience for guests, as a clean environment enhances both visual appeal and customer perception of the establishment.

While other actions like preparing food, serving customers, and plating desserts are crucial to restaurant operations, they do not align with the specific function of an "Expo Sweep," which is primarily focused on maintaining cleanliness in the dining area. This is why option B is the correct choice.
