Star hotel cleanliness

Once a guest checked out, our cleaning aunt went in to clean it and went into the room to have a look. It was fine. The guest is not dirty. First of all, clean the bathroom and flush the toilet. The toilet is clean. The water was full of shit. When I opened the toilet tank, I didn't know that the guest pulled it like this, but it was all in the toilet tank. The water was washed, ugly and dirty. After doing it for several years, the hotel thinks it is wonderful.
