The guest paid 200 for pre-authorization, but he didn’t pay attention to find cash when checking out. The hotel completed his pre-authorization for 200, so will the money be returned at the end?

Yes, Late charge is successful, but it is a credit card paid out, that is, cash out. However, the amount is small, so the bank will not object, and it is normal, but it usually requires the customer’s signature. Otherwise, the customer can refuse to pay.
