Yeah, right? That’s my experience, too. I feel like outdoor latrines charge like a coin, presumably to keep people from squatting in there, but most places don’t even have those. Maybe otherwise people are conflating customer-only toilets with paid toilets? I’ve never seen a paid toilet in an airport, though, and only once in a train station, and people seemed to be quite pissed about it and using the restaurants’ facilities instead.
