A mop moves in and out of the water full of dishes.
Food is laid out on the floor, which the staff often treads on, and sometimes it is cleaned with a mop.
It appears to be a video filmed at a Chinese restaurant.
People who saw the video expressed their displeasure, saying it was unsanitary.
On the other hand, there was an opinion that a mop used only for washing dishes would be okay, but there are also voices that it is necessary to file a complaint against a restaurant with a problem as consumers' level of hygiene has increased.
