Have you looked into mystery shopping? It really doesn’t pay much, usually a couple bucks above the required purchase, but you can get paid to eat fast food or donuts, or go to the movies. Some companies post full day audit jobs too. I know when I was strapped for cash having a couple bucks to go to Taco Bell instead of eating out if the fridge at my parents was nice. You can gain experience in what expectations are in different service jobs, too.
