How to deal with the hotel waiter opening the door for guests

Hotel attendants are generally not allowed to open rooms without authorization, especially without knocking at the door.

However, if the guest is in the room, first of all, apologize to the guest and explain the origin. Generally, there will be some situations, such as opening the wrong door, reminding to check out, continuing to keep clean and collecting money. Be sure to explain clearly to the guests and avoid complaints.
