M: Good evening. Is that Mrs. Philips?
W: Yes, it is.
M: Well, Mrs. Phillips. This evening, (19) I’m calling to offer you a special discount on...
W: Ah, no, let me guess. You want to sell a subscription to the newspaper or a great deal on the airfare to Hawaii, right? Or, you want to offer me an unbelievable bargain on dance lessons?
M: No, no, actually...Mrs. Philips. Oh, sorry. That was the last guy. Uh, (20)we want to offer you a free membership to our sports club downtown at the introductory price of $39.95...
W: Thirty-nine ninety-five? I thought you said free! Uh, listen, I’m not interested.
M: Well, it includes unlimited access to all our facilities, including the gym, weight room, tennis courts, and swimming pool.
W: Again, I’m not interested. I have my own fitness program I do around the house anyway.
M: Well, this is a once-in-a-lifetime deal. In addition, the location of the sports club is near your house. That will be convenient for you.
W: Like I said, I’ll pass this time. (21)And please put me on your "don’t call" list.
M: Okay. It’ll take between four and six months before your name will be removed from our database. You might be called by another representative during that time.
W: Ah, man. Ah, great.
M: Have a nice evening, Mrs. Philips.
