A man looks up from his book on his usual subway commute and sees a hamburger suspended in the air. The twirling snack collides with a second burger and sends sesame seeds and bits of flame-broiled beef across the subway car. Dozens of hamburgers appear and begin to bounce off of windows, handrails and other passengers. The man suddenly breaks free of his daydream and all of the food falls to the floor. Postmates says that when all you can burgers is think about, you should use its service.
