They’ll Serve You Dirty Food

As gross as it sounds, waiters and restaurant employees will serve you dirty food. If what you ordered happened to fall on the floor, or accidentally get sprayed with dirty dishwater or worse, they’ll still slap it on a plate and let you eat it. If they have to start cooking your meal from the beginning, then it just means slower turnover of customers and less tips for them.
