What's the state of public toilets in the US? Are they usable and clean? Because that's why you pay for them over here, to make sure someone keeps them clean.
They're pretty good where I live. Inner city toilets are often locked. Some stores will always have one clogged toilet (which probably reflects more on that specific establishment). But most of the time they're in good enough shape.
They mostly don't exist.
That is one way to solve the issue I guess...
I wouldn't trust a blanket statement like that on a ciuntry the size of the US. They are common on the west coast at least.
Not in my part of the urbanized west coast. I'm not aware of any at all. They used to be fairly common, but were removed a long time ago.
