Star hotels are more formal. Generally, waiters work in three shifts in the morning, noon and evening, and the working time is generally 8 hours, with 2 days paid vacation every month.
Mid-range hotels usually have two shifts, and they also have two days off every month, 10 in the morning and112 in the evening.
There are basically no shifts in low-end hotels. Generally, I go to work around 9: 00-10 and get off work at night 10-12. There are few waiters, so there is generally no specific rest day, so we have to ask for leave.
