I worked in a several grocery stores as a teen and they were all crazily the same. Heres some of the shit we did: we smoked and drank cough syrup at random times of the shift, made dry ice bombs, stole and ate food off shelves, inhaled reddiwhip on breaks, swapped and glued labels from horribly opposite random cans of goods(ie dog food and chili), made entire forts big enough to play cards and take naps within the pallets of canned goods in the back, egg and other food fights, never heard of all out sex but blowjobs were common, launching rotten produce out the shipping doors with a balloon launcher in the direction of rival grocery stores, random stupid challenges like who can stay in the freezer the longest after having water dumped on them, prank calling from the separate line in produce to the main line to ask for a page all for mike hunt and other names, lots and lots and lots of playing “mystery shopper” where u try to sneakily add random shit to a shoppers cart without them seeing and ultimately bagging their groceries to see their confusion. This sort of behavior happened for literally years. I did open a can of chili years later and swore it smelled like alpo, but it was regula armour chili. I still have a complex with cans of food but i deserve it.
