What if the guest breaks the glass door at five in the morning?

If the glass door of the hotel is broken, it depends on who broke it. If it is this glass door, it is broken because of poor quality. That must have nothing to do with hotel guests.

If it is because the hotel guests accidentally hit the glass door, the glass door will break. Then maybe both sides have some responsibilities.

If the hotel guest breaks the door artificially with something, it should be entirely the responsibility of the passenger.
