I spent twelve years running a vending route- we would sometimes put “healthy” snacks in the mix (baked chips, granola bars, that sort of thing). Then we would be obliged to throw them away once they went out of date (as they always did). Meanwhile I had to have two rows of Snickers and M&M’s in every machine (even the ones that I filled three times a week) to keep up with the demand.
The vending machine is for "Jerks! I work with Jerks! Better sooth my soul with chocolate" moments.
