I don't know, I'd rather them use a toilet that is self cleaning than do it on the trash bins outside my condo. I've lived in Brooklyn (Williamsburg) for a long time now, and the un-housed people that hang out up the block or sleep in the HSBC aren't happy about having to go to the bathroom in between parked cars on the street. Whenever I've walked by them while they're doing that (which is fairly often), they've always apologized. At least give them a clean, private place to do it.
