Ceiling Grid Saboteur

“Many years ago, I was a lowly production manager of a small team at a graphics shop. One of the dudes on my night shift got pissed at the shop owner and started taking tidy little poops on the ceiling tiles and then placing the tiles back up into the ceiling grid. An odor of poo started permeating the place, and nobody knew where it was coming from.”
“It took weeks to finally discover his high-altitude poop minefield. The owner grimly admitted, “I don’t pay you enough to take care of this crap” and broke out the ladder, face mask, rubber gloves, and bucket.”
