Set up drive through with a "holding" station for waiting and a board to show what orders are ready so you can leave the holding area. This could tie with several other suggestions but the order number would display when your order was ready and you could leave the holding station to pick it up (ideally already paid for either inside or via the Kiosk at the pump) but not too bad if you paid at the window. This would allow a) quick orders b) reduced delay at the pump as once I pay, I can finish pumping fuel vice waiting for the food.
