Disagree. I worked at a Dominos franchise for a couple of years. It didn't make much money. Delivery pizza is insanely competitive and relies heavily on discounts and coupons. Most of the labor cost is the delivery personnel who can realistically on average make about three or four round-trips an hour. You need a lot more drivers than you need in-store personnel and I would doubt that the amortized cost of a robot kitchen is much less than a minimum-wage human.

This sounds high to me. Just to be clear, are you talking about one trip out delivering to four different addresses before returning, or four trips out each to a single address all within one hour?

I guess it could vary a lot depending on how the store is set up. We had a limited delivery area that was generally no more than 10 minutes drive radius from the store. At the time we had a 30 minute guarantee so we tried to get the pizza made and out of the store in less than 15 minutes. Anything that went out over 20 minutes old was likely to be a giveaway.

So, 10 minutes out and 10 back is 3 round trips an hour. Often you could take more than one order per trip if the locations were along the same route.

Many common delivery locations were well under 10 minutes from the store so on average 3/4 runs per hour was possible for an experienced driver who knew the area and didn't get lost -- we had no mobile phones or navigation devices -- and didn't waste time.
