I used to live next to a drop in center in Staten Island. It was drop in, explicitly not a place people were allowed to sleep because voters/politicians would barely allow that, they really say/think, "There are no homeless Staten Islanders."

As I understand it there was one 'good chair' where they turned a blind eye if you needed to sleep for a while. But, there were frequently conflicts outside the place because someone slept longer than they should have, or at a different time, eating into someone else's sleep.

I know the issue is complicated but I really saw people knock each others' teeth out because they just wanted some rest.
