Back around 1990 or so, the company I worked for had a cafeteria. I always brought my own food to work, still do to this day.
Anyways, the gross guy who used to cook and run the cafe, he's in the mens room, takes a leak, leaves w/ out washing his hands, so I named him "Shake & Bake".
(Shook off his crank, went and made food for people).
Plus back then you could smoke, and he would cook food all day w/ the butt hanging out of his dick licker.
Im sure McD's workers spit in food, jack it in food, and just be lazy and grotesque. No different than the fancy restaurants I guess.
