Should the hotel bathroom door be closed at night?

Reason:

1, to prevent the smell of toilets and foreign bodies from floating out.

2. Prevent the teacher from climbing into the living room.

3. Turn on the light to expose low light to illuminate the floor, so as to get up at night. Closing the door can also block some light.

4, to prevent thieves, the toilet door is closed, there are lights, you will think someone.
