look at the pizza building cooking and delivery process....
it's gotten more efficient
instead of having some kid write down your info every time, then pass that paper to the kid cooking it, then having him roll the dough from fresh ingredients, cook it in a big oven, then give it to another kid to hop in his 84 oldsmobile and wasitng a lot of gas trying to find your house...
you have a computer telling a kid to pop pizza style A4 into an oven/Q unit. The timer beeps, and another kid hops in his tercel and travels to 1 of 4 stops using his GPS unit to tell him the best path to take.
