Denver is discussing this now. The only thing on the table so far are the self-contained toilets. There's no discussion of having a sort of self cleaning wall. I mean why not, people do that already and in the wrong place and it's not self-cleaning? And by people, I mean men. Takes a desperate woman to take a leak in public, but the two I've seen do it? They had the bravery, courtesy, and drunkenness to do it in the street gutter. I have never seen a man do that.

And then what about the public urinals in Amsterdam? Not under discussion in Denver either. It is admittedly sexist, but it's also mainly a dude problem.

You say "people" but do you mean "men" or does every female have a shewee?
