Mostly they're discreet about pissing in recessed entryways, but somebody tried to spit on me at a bus stop completely unprovoked, and there's more than one guy on Market around 3rd or 4th who would wander around and yell incoherently at pretty much any pedestrian within twenty feet. Some nights there was almost a Mad Max vibe to downtown.

They didn't merely stop the Muni/BART escalators. Those huge machines were clogged with so much shit that they failed. http://www.sfgate.com/bayarea/article/Human-waste-shuts-down...
