But what about when say a mcdonalds or subway decides to do it? They pretty much pre-pack most of the ingredients/food anyway at the distribution level. Get a robot to reassemble at the kiosk level... Being open 24/7 is a lot more cost effective. Waste is minimized. It will be a real game changer. Just in time service will be coming to a fast food place. The scale of cost savings will be too much for them to ignore.
