Or, not aim at the wall at all and urinate downwind...

Why there aren't more public toilets in major towns is a mystery to me. Here in Paris there are a few, but not enough by a long shot, and for some (puritanical?) reason they close automatically at 10pm, so if you're coming out of a bar or a restaurant late at night, you're out of luck.

What's the problem with public toilets????
