What if the hotel room attendant opens the wrong door for the guest?

If the wrong room is empty and clean, there is nothing wrong with apologizing. If the wrong room is a guest room, it will be complained by the guests in that room, which will have a bad influence on the hotel. It's best to apologize politely, then report to your own leader to see the attitude and reaction of the guests, and then cooperate internally and add value-added services.
