The toilets you cleaned in 1996 were no where near as disgusting/dangerous as what the public toilets look like now from fentanyl zombies and meth heads. I doubt you had to worry about pricking yourself on a recently used needle ever. Those people simply didn't exist on this level back then and there were more options. Please stop with the 'I hiked uphill both ways' routine... life is worse now than in 1996 in almost every way. We shouldn't be expected to ignore it and just put up with it. People should stop making excuses for it and address the root of the problem.
Meth and heroin were massive problems in the 80s and 90s. Go and watch Trainspotting which was literally made in the year you mentioned and then come back and defend your point about public toilets in the 90s not being drug litter riddled.
Yes, they existed, but definitively not in the same potency (i.e. fentanyl) or volume and were more expensive and harder to get. Not every public toilet in the 80s/90s was completely taken over by deranged homeless drug addicts like it is now. The problem is much more difficult. It's not the same at all.
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.
