Delivery took 2 hours and 2 minutes

I'm not even mad, moreso just flabbergasted by the absolute saga of the ordeal. I ordered at 7:30, delivery driver left at 8:02. I live about 5-7 minutes from this dominos. After 20 minutes I saw the driver just south of a town 20 minutes north, then when I checked again they were in a town 5 minutes south, then a town east of that one, back to my town, made a delivery ON MY STREET, passed my house to make a delivery 10 minutes north, then to my house. I was wondering if any drivers could let me know how the app works, does it just stack deliveries in order regardless of how silly that delivery sequence might be?
