Is it possible that there are many loopholes in the hotel system?

1. Now the hotel system is perfect, and I have never heard of missing bills.

2. Of course, there are no full-time network management personnel in a small area, and there will be loopholes in this respect. But no one will deliberately attack a small hotel. After all, the front desk or cleaning aunt may think that you didn't pay the house fee.

Therefore, it is not something that ordinary people can do, and it can be basically ignored.
