What does the hotel tail room mean?

The back room of the hotel is the room at the end of the corridor, and the hotel is rarely full. When assigning rooms to guests, they usually start with the room near the elevator lobby, because it is faster to provide room service and more convenient to clean the room after check-out. All hotels wish they didn't have a tail room, but the market is so big and there are more and more hotels, and the tail room will only increase rather than decrease. A manager who can control the existing room opening rate without falling is already a qualified manager.
