In Philadelphia, people do this on the subway. They pay a token to get on (or they ask someone for a token if they can't afford it) and then once they are on no one will ask them to leave.

It is a helluva thing if the best thing you can do with your day is ride the subway all day long, and some homeless people just feel safer on the subway (and I can't blame them).
