Try to find a bathroom in a tourist town in france and then get back to me. In america if you go into most shops and ask, they will let you into the bathroom. In touristy areas sometimes they are dicks about it, but still you can find a way. In france, if you don't have coins on you, they will literally watch your bladder explode. This isn't an american problem, I find it way easier to know where to go in the US (any mcdonalds, starbucks, etc... will let you in no questions asked)
