The hotel was fined. Reason: I work at the front desk and I have a guest. I gave it to him two days after the ID card expired, and then he said it was an unannounced visit by the police!

According to the normal procedure, since you have found that his ID card has expired, you should not open it. It's normal to say sorry, sir. Your ID card has expired, and I can't handle any services for you here. Since it's open, it's responsible.

There is also the customer who came to the hotel to check in when he knew that his ID card had expired. Isn't he crazy? Did he say it was a police unannounced visit or a police unannounced visit? I suggest you ask to see his police officer's card, but he has the right to refuse ... so if it is really not possible, you can call 1 10 to call the police, and then let 1 10 help you find out whether it is true or not. If it is a real policeman, and your hotel has no detailed management regulations on this matter, you can go through legal procedures.

PS: I suspect that the boss and the customer colluded to cheat you.
