What weird things have you encountered while staying in a hotel?

One year I went to Nanjing on business. Because I often stay in hotels, I applied for a membership card for an express hotel chain a few years ago. This hotel chain has pretty good hygiene in every city. The environment is also very suitable. When I checked in the night before yesterday, I told the front desk that my sleep quality was not good and I wanted a particularly quiet room. The front desk gave me the room at the end of the sixth floor. By 12pm. There was the sound of a young mother leading her child next door. I think it turns out that the walls of this shabby hotel are not soundproof. But it was already 12 o'clock, and I was basically going to bed when I came in to take a shower, so I listened carefully. As a result, I heard the sound of the young mother next door playing games with her child. I thought, Damn, it’s already past 12 o’clock, you’re not sleeping, and you’re still playing games! So I endured it. It was 1 o'clock and I was still playing games. I couldn't bear it anymore and called the front desk to complain. The front desk said, I didn't arrange anyone for you next door to your room because you said you couldn't sleep well and wanted to be quiet, so I tried my best not to arrange someone for you next door. I said come and take a look. Then an employee knocked on the door. I asked her to come in and listen, and she heard it, so she took the key and opened the door next door. When I opened it, I found that no one had ever stayed in the room.
