Funny, I go to South Korea and the fast food burger joints literally operate exactly as you say they couldn't. I've had the best burger in my life from a McDonalds in South Korea operated practically by robots.
It's a non reality in America's extremely piss poor restaurant industry. We have a competency crisis (the big key here) and worker shortage that SK doesn't, and they have far higher trust in their society.
