I saw men peeing outside a number of times in France and Holland. I watch 2 couples get out of a Mercedes at an ancient cathedral. The women walked one way and the men walked over to the wall of the cathedral and peed on it.
Be glad it is only street bums doing it in SF, it could be everyone.
Ten years ago in Kaiserslautern....I had to go downtown and park in a city parking lot (enclosed) and as I exited....here was some half-drunk 16-year old German kid (10AM)...fairly wasted, and attempting to pee while leaning against the wall.
Now, I noted that directly behind this kid (2-feet) was a pipe that exited the building and was head-high. I stopped ten feet from this anticipated event and watched. Sure enough...the kid finished with his public urination event (at least 30 people could stand and watch him)...did a 180-degree turn, took one step forward and whacked himself in the head. He flew backwards and landed in his pee. I wish I had taken a photo of the event.
Urinary and fecal sheek.
