Is it reasonable to charge overtime in the teahouse at night?

Reasonable. According to the teahouse charging standard, the implementation of the teahouse charging standard at night is to ensure the normal operation and service quality of the teahouse. In the evening, the service staff of the teahouse need to work overtime, and the number of customers is relatively small, so it is very reasonable to charge overtime. The charges for ordinary teahouses are: overtime in private rooms 15 yuan service charge, and overtime in large rooms/20 yuan service charge.
