I don't understand my clients sometimes. Some of them use paper towels for toilet paper. They know they aren't supposed to. They are homeless, not feral. Isn't toilet paper cheaper on the whole anyway? And I always have a stock of free toilet paper I can give to them if they ask. So, every few months the plumbing gets clogged by paper towels, everyone complains, the houses smell, and we never get a plumber till the next day. Everyone is told not to use paper towels as toilet paper... again. Next day, someone tells me they found a paper towel in the toilet. So the ones who value common sense fight this. They put up notes in the bathrooms. "FLUSH THE TOILET AFTER YOU'RE DONE" and "DO NOT USE PAPER TOWELS." These are nearly always ripped down... I'm not sure if it's out of spite, or because it's obvious to some of them that they shouldn't flush paper towels, or because it's not posted by me. So a guy gets his note ripped down 5 days in a row. He's getting pissed. What does he do? He writes the message on the wall with a sharpie in 6 inch letters. Then he gets pissed when he gets in trouble for it, because he was just trying to help stop the morons using paper towels to wipe their asses.
This makes the problem much more interesting and slightly more intractable. I wonder what would happen if you provided them with free, top-of-the-fucking-line, premium Cadillac toilet paper. Like, tp so good that they'd be craaaazy to use a paper towel. Fuck 3-ply, you should track down some 4-ply and set it free. See what happens.
