I've been delivering via postmates for the past week now in New York City. To my great surprise, deliveries to "bad" neighborhoods, people who seem regular/lower-middle class and taco bells drunk runs net me the biggest tips. On the flipside, I ordered and delivered $270 worth of food to a posh area in Brooklyn. The rich lady was nice and all smiles, but no tip, at all. I'm not bitter about it, comes with the territory, but I want to know what kind of twisted psychology drives the rich to act like this.
