Aren't hotel guests responsible for sneaking people into the bar?

The front desk is only responsible for the registration of inbound passengers, and the front desk is passive. The front desk knows that there are many people living together. If only some passengers register, the front desk is responsible. If only one guest is registered, others are not registered, and they choose to sneak into the hotel, which violates the relevant regulations, and the responsibility is borne by the passengers themselves. If the front desk finds that the passengers are not reminded to register but let themselves go, the front desk is responsible. If the guest refuses to register, the hotel should refuse the guest to stay. If the guest forcibly checks in, the hotel can call the police.
