I used to work at Domino’s as a delivery driver and I can tell you from personal experience that we don’t really care how you’re dressed. I’ve had people answer the door in just a towel or looking like they’ve cried a five gallon bucket worth of tears. We’re there to bring pizza (or other foody) goodness into your lives. Also - fyi, if you give a tip in cash we’ll love you forever. We don’t typically have to include that in taxes cause our bosses don’t care. Means we can fill up our gas tanks.
