W: Excuse me. I’m looking for someone who can help me with the textbook reservation program.
M: Oh, well, I can do that. What do you need?
W: Okay. Um, my friend told me that I could get used books if I order, I mean, preorder them now.
M: That’s right. Do you want to do that?
W: I think so, but I’m not sure how it works.
M: Actually, it’s fairly straightforward. We have a short form for you to fill out. Do you know what you’re going to take next semester?
W: Yeah, I do.
M: And you have the course names and the schedule numbers for all your classes?
W: Un-huh.
M: Okay, then, just put that information down on the form and, uh, make a checkmark in the box if you want recommended books as well as required books. And you said you were interested in used books, right?
W: Right.
M: So mark the box for used books, sign the form and bring it back to me.
W: Do I have to pay now? Or, do you want a deposit?
M: No, you can pay when you pick up the books.
W: And when can I do that?
M: The week before classes begin.
W: That’s good, but, um, what if I change my schedule? I mean, I don’t plan to but...
M: ... it happens. Don’t worry. If you change classes, you can just bring the books back any time two weeks from the first day of class to get a full refund.
