I can tell you what they didn’t find. When I worked at Denny’s when the health inspector came the cooks took all the expired food out of the fridge and stored it in their cars and by the dumpster until after the health inspector left and then they put it all back. I ended up quitting that job after I got written up for refusing to change the dates on the labels of all the expired food, which was one of the primary jobs of the graveyard server.
