In the tradition of nothing is as good as it sounds, I would have to say the most disgusting bathroom of all my jobs was at Barnes and Noble. This was especially problematic because I had to take a job there after the old 9-11 incident. I graduated college right after the event, and people who had gotten jobs were getting laid off. I got two interviews: one at CUTCO knives, and one at Barnes and Noble.
So there I was, a UCLA graduate, with this dicknose manager who was all B&N corporate pride expecting me to clean up the swamp-like bathroom and run all the junkies, drunks, and homeless out of there. It wasn't like I was above sweeping poop into a WetVac -- but for B&N? Fuck no.
It seemed like every day there was something -- poop-tipped condoms, diarrhea spinney splatter (at shoulder height -- I have to assume it was an infant being turned toiletside in an emergency), bloody poop, puke on the floor, poop kind of in/on the toilet (I think from the infamous Double Dragon), or blood on the floor.
Floods, bloody tampon and poop floods (in the men's bathroom?), socks with poop in the toilet floods.
Heroin needles in the toilet complaints, heroin addict shoes on the sink with heroin addict asleep on the floor in the bathroom complaints, heroin addict asleep in stall with socks on and arm coming out from stall with needle still in it complaints (shoes found later in cafe).
Pee pee in the sink, pee pee filling the sink, pee pee on the toilet paper (ALWAYS -- who pisses on the toilet paper every day!? What kind of warped tradition is that?).
Spit, chogies, big slimy green and black chogies on the mirror and hanging from the ceiling.
Poop smeared on the mirrors, covering the mirrors in brown translucent poop and with the sinks ON, overflowing with hot water.
Homeless people smoking in the bathroom and begging for change, homeless people begging me for change while I was taking a shit and then trying to have a conversation over (!!!) the stall wall.
Porn in the toilet.
Graffiti (written in poop).
People fucking in the bathroom, man on man, man on woman, woman on man! People going at it, just fucking in the bathroom, in this environment!
And for every one of these -- AND MORE!!! -- the management would expect ME to clean them up or stop this or that from going on. And every time, I would say, "That is what *you* get the big bucks for," or, "I can't afford to inhale any fecal chloroforms right now with my t-cells where they are. I could get pneumonia and die."
They would know I was fucking with them. They would try to get me to clean it. They would threaten me to make me clean it. I wouldn't. I never cleaned it. I would tell them to write me up. I would tell them to fire me. I would tell them I would do it, and then put an "out of order" sign on it and go home, leaving it, whatever it was, for the next shift. Fuck Barnes & Noble. This was the most fucked up bathroom at any place I ever worked. I even stopped using it. I would sneak over to Nordstrom and use theirs on my one hour, ten minute break.
