I can’t find it any more but I saw the issue of a trade journal Nation’s Restaurant News years ago that showed a body of a young woman in a body bag being carried out by the EMT responders after being murdered by a customer at a fast food place.
The article mourned the loss of yet another worker and said people believe an astronaut, a race car driver or a police officer is at risk of their lives and know what dangers they face but actually, more injuries and deaths occur to minimum wage workers such as food workers than those professions.
My own experience at age 19 included working as the delivery driver for a totally independent pizza place in Detroit owned by an Italian family (there were no major chains then). I got the job because it was open. The last guy quit after he had been robbed by two men who held him with a knife to his throat in the dark.
Me, it was Dominos, and a guy robbed another driver.
He delivered the pie to the address, the guy met him at the door with a gun. Took the pizza AND his money.
When the cops showed up they found him at the table, with his gun, eating pizza and counting money.
I worked at gas stations a lot in my youth. The last day I worked in one was when I came in and found the previous shift tied up in the bathroom and the register cleaned out.
