* * That's right * *, if you use balloons in a hotel room and stick them on the wall, you have to clean them yourself. The hotel waiter may puncture the balloon, but it is a waste, because the balloon you bought may not have been used. Moreover, if the fragments of the balloon are left on the wall, it may cause harm to other guests and may also cause losses to the hotel. Therefore, it is the most responsible way to clean the balloon yourself.
