I think it will be more like the "self-checkout" stations we see already at grocery stores. Instead of 3-4 people cooking, and 2-3 people taking orders at the counter/drive through, it'll be a bunch of "robots" cooking the food, and a self-service ordering station, with one person that oversees the robots, and one person overseeing the registers. Unfortunately, you usually need a human being to handle exceptional situations whether it's the human beings making mistakes, or the food preparation going wrong.
