Cleaning up bodily fluids, which likely come from drug users, is a whole other thing.
OK, come on, you don’t know that. I doubt we have any serious data that bodily fluids in public bathrooms are likely to come from drug users. And if you’re cleaning it up, presumably you have equipment and are not using your tongue, the residual drugs won’t jump on you. Don’t stigmatise hard drug users, many of them (maybe most) were given a rotten hand early on and now want help. Policies such as Portugal’s decriminalisation have shown we can make a bigger difference when we treat those people as people.
Either way, the point of your parent comment is that most people don’t even pick up trash, which is itself a problem.
There was an immediate 90% reduction in bodily fluids outside the toilet bowl and 100% reduction in stolen plumbing (they were taking part of the p-trap for drug use) and in finding discarded paraphernalia. Correlation isn't causation, maybe all the crack heads were still using the bathroom but decided to be civilized, IDK, but keeping the bathroom under literal lock and key was a big benefit.
It was inconvenient for customers, that was true, and I didn't like that aspect, but it was hard getting staff (or even myself) that had the will to hose poop off a bathroom wall.
Which I can tell from your comment you've never done. "presumably you have equipment" Yeah, a hose. A mop and bucket. You're still in close proximity, you still step in it, it still splashes. And nothing prepares you for the smells. And you can never unsee it. I won't even describe the things I saw in the womens bathroom. Way less common for things to go down in there, but when it did... It's wretched work.
When I was a kid growing up in the 80s/90s, you rarely saw homeless camps like they are now where they openly use drugs. You never saw public restrooms that were completely disgusting. Fast food bathrooms were clean back then.. now they are horrible. Things are not the same... The worst bathrooms back then were at the public parks where they were covered in pee and not cleaned well, but weren't destroyed by drug usage like they are now. I don't remember seeing piles of needles (or even one needle) like you do now.
And, honestly? If more people had to clean toilets in use by other people, maybe we wouldn't have so many folks expecting other people to clean up after them. I see countless posts in my Facebook group about trash on the street. In the time it took to take a photo and post it to social media, they could have picked up the trash and taken it to a nearby bin.
But I suppose that experience goes two ways. Some people think they're above the human condition, to the point where they won't even clean up after themselves, even in their own homes. And other people recognize that it's actually not that hard to clean things up, if you just do it. We all have good and bad days.
