The only people I feel sorry for are some of the elderly. I noticed in Florida, in some small towns, the fast food joints were staffed with old, white retired folk. They were slow as hell, but they were so friendly and charming to talk to that I didn't mind. I'd hate to see them replaced by machines.
Around here though (DC area), I always take the machine check out over the unfriendly, unpleasant and incompetent checkout out bitches. I welcome the our new ordering machine overlords!
