The hotel forgot the check-out card.

Employees do not take full responsibility, but they do take some responsibility. Obviously, the hotel's front desk management system is not perfect, and the hotel needs to bear most of the responsibilities.

In addition, as a receptionist, it is a routine procedure for guests to take back their room cards when they check out. Don't forget, even if you don't take it back at that time, you must write it down.

As a hotel room attendant, I don't know if there are any customers in the room, which shows what kind of hotel this is.
