There was a sound of shaking the key chain in the hotel corridor.

There are many rooms in the hotel, so it is normal for guests to come back late. There is no need to make a fuss.

When a guest knocks on the hotel door in the middle of the night, he usually finds the wrong room. Under normal circumstances, the security of the hotel is very strict and there are cameras. It is difficult for thieves to sneak in to test whether the guests are there. After all, they stayed in a hotel because they stayed at night.
