Narrator Listen to a part of a conversation in library. Why does the librarian ask the student about her favorite videos?

[Librarian] Hello, Can I help you?
[Student] Yes, I’d like to join the video library. Is this the right place?
[Librarian] Yes, it is.
[Student] So, what do I need to do for that?
[Librarian] OK. All you need to do is to fill out an application form.
[Student] That’s good. Can I get one now?
[Librarian] Yes, of course. Would you like to fill out the application form now?
[Student] Yes, I can do it now.
[Librarian] Hold on and I’ll get a form...
    Yes, I’ve got it. Please fill it out. Oh, don’t forget to sign at the bottom.
[Student] Right...
    Here you are. Is it OK?
[Liberian] Mm, yes. But I still need a little more information...and your telephone number? I need both home and work.
[Student] Home is 9835 6712 and work is 9456 1309. Do you need any ID or anything like that?
[Librarian] Yes, we need your driver’s licence number, that is if you have one.
[Student] Yes, I know it by heart; it’s an easy one, 2020BD. Do you need to see it?
[Librarian] No, that’s not necessary. Right, thanks. That’s the most important part by the way, but could I just ask you a few questions for a survey we’re conducting?
[Student] OK.
[Librarian] What kind of videos do you prefer to watch? Have a look at this list.
[Student] Well, I love anything that makes me laugh. I just love to hear jokes and funny punch lines. I’m not very keen on Westerns, although my father likes them, but I’m a real softie, so anything with a bit of a love story is good for me. It doesn’t matter how old. Not musicals though, they’re too much!
[Librarian] Anything else?
[Student] I am completely taken by documentaries of the great outdoors, you know the sort, animals, plants and far away places. I saw a wonderful one on dolphins last week. It was amazing.
[Librarian] Now, I think that’s all from me, except I need you to sign here on the line. Here’s a pen. Oh, and I nearly forgot, the membership fee, $ 25, refundable if you leave the library for any reason.
[Student] There you are. Do I sign here?
[Librarian] Yes, that’s it. You can borrow videos now, if you like, but your card won’t be ready until next week. You can come and pick it up when you bring your first videos back. That is if you want to take some now.
[Student] Yes, I’d like to. I’ll have a look around.
[Librarian] Fine.
