What is the probable relationship between the two speakers? [br] [originaltext]

W: Can I help you?
M: Yes, I’ m looking for a book on the presidential election system in the United States.
W: Well, all of our textbooks are arranged by subject and course number in the back of the store. Is this a required text for one of the University’s political science courses?
M: No, it isn’t. I’ve already looked through all the political science books in the back, but the ones I saw only had a few pages, at most, on the topic.
W: How about the paperback section? There may be something there.
M: Okay.
W: Or better yet, you should try looking in Books in Print.
M: I’ve never heard of that. What is it?
W: It’s an index that lists all of the books currently available from publishers. If you have a specific book in mind, you can look under the author’s last name.
M: But I don’t.
W: Then look directly under your subject, presidential elections.
M: What happens if I find a book I want?
W: Well, if it’s not in stock, we can order it for you.
