I went out to eat at a restaurant last week and got up to go to the restroom. As I was walking by the kitchen, I watched a cook drop a piece of chicken in the floor and put it right back on a plate. We left right after that.

We proceeded to leave the restaurant, but not after informing the manager, very loudly, about the incident.

Yeah, I wonder what their bathrooms are like if that's their service
