Where are the two speakers?

W: I’m sorry, but I can’t let you check out these books.
M: What do you mean?
W: Well, the computer shows you’ve got an overdue book, Art Work. And you can’t borrow any book until you return it.
M: But that’s impossible. I only started going to this school last month. And I’m a business major, not an artist.
W: Hmm. The thing’s pretty strange. Let me look up the records. OK, you are Robert Smith?
M: Yeah.
W: You live at 1423 West Conner Street?
M: Ah? No, I’m living on campus now.
W: You did say you were Robert Smith, right?
M: Yeah. Well, my full name is Robert James Smith.
W: Let me check one more thing on the computer. I see now, there’s another Robert Smith, Robert El. Smith. And it looks like he’s the one who got that overdue book checked out.
M: Another Robert Smith, no kidding?
W: So I guess you two never met.
M: No, I’m thinking I should probably try. I could at least find out what has just happened.
W: Good idea. Now I let you check out these books today. But I suggest you should start to use your middle name to avoid any problems like this in the future.
