It's been a long time since I was in a McD's, but even years ago they had touch-screen kiosks for ordering, which were great. I think the whole restaurant had maybe 6 employees in it, most in the kitchen. There was one girl handing orders to customers and that was it for front of house.
This is the way it should be, and this type of automation will soon be wide spread, except in places like California, where the locals will vandalize the kiosks, shit in the lobby, etc. In those places, the company will just close their stores. It's for the best.
