M: Hmm, hi.
W: Hi, I am going door to door tonight to carry out a survey about student’s eating habits. Do you have a few minutes?
M: Sure. You know, I think I read something downstairs in the notice board.
W: Yeah, there was a notice about us there. See, we are trying to figure out what students like to eat most, how much they’re willing to pay for that…things like that.
M: That’s right. You are doing this survey for the cafeteria on campus, right?
W: That’s us. We just feel it is important to serve you guys with something really attractive—I mean both taste and price. Some complained our menu hadn’t changed for years.
M: Really? That’s definitely good news. My friends and I always eat there.
W: Then would you please do me a favor by filling in a questionnaire? And we’ll send you a breakfast coupon as a reward.
M: That’s excellent. Let’s begin. Oh, can I borrow your pen?
W: Sure. Here it is. Okay. Please sign your name at the end of the questionnaire, here. And also here on this form to get your coupon.
M: Sure. Here, and there.
W: That’s great. Here is your coupon. Oh, one more thing. Let me leave you this card with our opening hours and telephone number on it. If you’d like to order any take-away, just call us.
M: Yeah, that’d be useful. Thank you, bye.
