5-star hotels enter other people's rooms without permission.

Look how you got into the room. Housekeeping will clean your room every day. Generally, five-star hotels start cleaning rooms for guests at 8: 30 in the morning. I have to wait until I meet you every day to ask if I can clean the room. If you come back and find that your room is not cleaned, you will complain, won't you? There are also some routine checks. If the security department finds danger, the engineering department has to ask your permission to go in, right?

But if you are in the room and they push the door in, that's easy to say, but usually a five-star waiter will knock on the door three times, and there must be a five-second interval between three times. If no one answers, they will use the master key to open the door, and then knock on a small crack with their feet to make sure that no one enters the room again, just to cause misunderstanding, but if there are guests, they will deliberately not open the door, and the waiter should not open the door. There are also many complaints.
