I think it’s been like 20 years since I had to use a truly public toilet.

Is this really such a common occurrence for people? Because I feel like toilets are being discussed way too much.

Do you not have a bladder? Do you never leave home for longer than a few hours? Are you aware that some people may have smaller bladders or produce more urine for various reasons?

If anything, toilets aren't discussed nearly enough. There is a huge lack of public toilets pretty much everywhere in the world.

Yes, most people have to use a toilet occasionally?

I can personally attest that having mild gi issues can make most of Europe a bit of a hellscape, with their expensive and simultaneously gross toilets. As an Australian I never appreciated clean public toilets before going there.
