Was in line at a local fish and chip shop that sells more than just fish and chips (burgers and other types of fast food fancies) and witnessed a worker there poking holes into raw meat with his fingers. Literally playing with the raw meat as if it was play-do. Only to then start messing with food that was already cooked. Other customers must have seen him do this, but they remained there. I, on the other hand, walked out of there. I haven't been back since.
p.s I have used this fish and chip shop for longer than 10 years and the thought of it turns my stomach.
