These go back 70+ years. Walk in and there is an array of glass doors with delicious meals behind them, ready to eat. https://en.wikipedia.org/wiki/Automat https://en.wikipedia.org/wiki/Automat I remember 1980s McDonalds, where they had steel rows of styrofoam encased Big Macs and Quarter Pounders behind seven tills of staff, with little metal separators telling the time they were made so anything older than 10 minutes was sent to the garbage. This was before drive throughs, but even with a line five deep you'd be out in 5 minutes at noon. My boss would take us for lunch every day, it was amazing.
