When I worked at McDonald’s (1974 the paper hat and blue barber shirt era). We called a tray of Big Macs that looked especially good “Movie Macs”.

In 1972 when I wore the MickieD’s sailor suit and looked particularly cute we had Big Macs for breakfast lunch and supper.
Never cared much for the Mac myself. The fries were the only station I could work all day and still want to eat them. Of course they were still cooked in lard then.
Tricks we played on folks we didn’t like... cook some apple pies in the filet-o-fish tank, “forget” to break the yolks on the egg mcmuffins so they’d squirt when bitten into.
