Why lock the refrigerator when staying in a hotel room?

The refrigerator in the hotel room is locked to prevent guests from putting any prohibited items or items not allowed by the hotel, such as alcohol and tobacco. In addition, locking the refrigerator can also prevent guests from adjusting the temperature without authorization or damaging the internal equipment of the refrigerator. The main purpose of locking the hotel refrigerator is to ensure the overall safety of the hotel and guests.
