Maybe houses have many bathrooms, but my experience from the US was that it is incredible hard to find public toilets which is very annoying when you're a tourist.

When we found one, they were pretty disgusting. Even places like Starbucks didn't even have a toilet. I mean what the hell? How can you serve people coffee which makes stomachs rumble without having a single customer toilet?

From a European perspective, this was very uncomfortable and I also have a condition which makes my stomach untrustworthy.
