Imagine someone mixed mustard and chocolate pudding together and then smeared it everywhere, then mixed that into syrup and poured it into every drain they could find clogging it up.
I once worked at a grocery store as a "customer courtesy clerk," a fancy way to say, bagger. One of the jobs is cleaning the parking lot, the produce zone, and the bathrooms. Late one night after closing, I was unfortunate and had to do the bathrooms. The women's restroom was its usual gross self, but the men's room, holy Jesus. The sinks had diarrhea or puke in them, they were clogged and full to the brim, the urinals, the toilets, everything was clogged and full of or covered in shit. The shit was up the walls and on the mirrors. I had never seen such a thing, it was enough where I would have puked had the toilet not been full of someone else's shit. I did my job by going through three clean mops and a couple of gallons of bleach. I transferred out of that job quickly after.
