M: Hello ! University Books. Tim Weber speaking.
W: Hi! Tim, this is Ruth.
M: Oh, hi. Ruth, What’s up?
W: Well. The Student Federation needs a couple of volunteers to give guided tours to the new students during orientation next week. Would you be able to help out?
M: That depends on the days you had in mind. I’m working here fulltime before classes begin, it’s really busy now, with all the textbook orders coming in, but I do have some time off.
W: What about Saturday? Most new students arrive on the weekend.
M: Sorry, I have to work all day Saturday. How about Thursday and Friday? I’ve got both mornings free.
W: I don’t have the schedule on me...Ken’s got it. Maybe you can set something up with him.
M: I only be able to spare a couple of hours, though.
W: No problem. I’ll ask Ken to get in touch with you later today. Will you be at this number?
M: Yeah, till four...Look, I’ve got to go. I have to get all the order out before I leave today.
W: OK, thanks, Tim. Bye.
