How many managers does a hotel with more than 80 standard rooms need? What is their position? Ask the great gods to summarize the structure of a word ~

A manager and a supervisor (or supervisor and foreman, this is arranged by themselves, with similar meaning). Usually, the supervisor makes rounds, and the manager takes the place when the supervisor is resting. As for waiters, if the off-season is obvious, it is more cost-effective to leave about three waiters and recruit temporary workers in the off-season. If the off-season is not obvious, leave about six waiters. This is based on the daily handling capacity of service personnel in five-star hotels. There are about 14 rooms every day, which can be adjusted up and down according to one's own waiter's ability), plus about 3 room clerks, who are responsible for answering guests' calls, communicating with other departments and sorting out office materials.
