This exactly. Having been a former franchisee of one of the big three pizza companies, I can attest that this is true. On a typical evening there could be as many as 30 to 40 deliveries in the store per hour. With that kind of volume, it is easy to route drivers where I can send 2 or 3 orders together to the same geographic area. It's just logistically easier when there is a high volume of orders and the geographic area of the store's delivery zone is small.
