Who knows if this situation is a crime? What crime?

This behavior does not constitute a crime, because these drinks have been paid by the guests, which means that the ownership of these drinks belongs to the guests rather than the hotel, so the hotel has no right to deal with these drinks. As a hotel, if it is stipulated that drinks cannot be taken out of the hotel, it is only a discipline within the hotel, not a law. However, if the guest pursues these drinks, you should return them to the guest. The hotel has no right to pursue these drinks, but if you don't return them to the guests under the investigation of the guests, it is illegal, so this kind of behavior is not illegal, but it is not illegal!
