There was a line in the book “Blue Highways”, as he travelled around the US eating mostly in diners. Something like “When there are 50 kinds of jelly out there, why is it always grape?”
My hotel in Amsterdam had a robot waiter. A human took your order, and then the robot brought your food to the table, and a human would unload it and place the dishes in front of you. I don’t think it swept up, though!
They come out in the order originally published. Their “year” is just out of sync with real life.
