What does the term "wait" refer to in a restaurant context?

In a restaurant context, the term "wait" typically refers to when all the tables in the restaurant are full. This situation signifies that there are no available seats for new guests, requiring them to "wait" until a table becomes free. The staff manages this by taking down the names of the guests and informing them about the estimated wait time, thus ensuring a smooth flow of service and guest management.

The other choices describe different scenarios in dining but don't accurately capture the definition of "wait" in this context. For example, the period between courses is generally referred to as service time between courses, and the time taken to prepare food relates to kitchen operations rather than guest seating. Lastly, while a line of guests waiting to be seated certainly encapsulates an aspect of the situation, it’s the full occupancy of the dining area that primarily defines the waiting status in terms of seating guests.
