If only they could roll out a robot that could actually get an order correct...then we'd have something. It's easy to type the order in correctly, but to get the person filling the bag with food to do it right...that seems a challenge beyond decades of trying.
Maybe if the bag filler got paid $13/hr instead of the below poverty wage average of $7.75, they would try harder to ensure everything's correct since it would be a valuable job to lose.
