I have been raised on English, but you could always try hitting up a fast food place. There is going to be at least one person there who's ESL. You just said person, so I'm assuming it doesn't have to be a student.
Or hell, ask the janitorial staff at a school you do have access to. Sorry to play on stereotypes, but those are the easiest places to find people who are recent immigrants/citizens.
I think the adult workers would have more interesting ESL stories too, because students have the advantage of being in school and learning it there. Most adults who come to this country and don't know English have to get creative about learning it.
