Food hygiene

Visiting a village, today we went for lunch in a small cafe , we ordered lunch and my girlfriend asked to use the toilet ,they handed her the key and off she went locking toilet door behind her. She returned immediately saying can we leave NOW, I followed her out side and she explained the toilet hadnt been flushed and had brown stains ,the sink was no better .Our appetites disappeared snd we went back to the car and drove back.
