W: Good morning. This is Dr. Anderson’s Office. May I help you?
M: Good morning. I’m Johnson. My friend recommended Dr. Anderson to me. I’d like to make an appointment with him to have my teeth checked.
W: I can arrange for you to see the doctor two days from now.
M: Can’t I come in tomorrow?
W: I’m afraid Dr. Anderson won’t be able to see you then. He has a full schedule for the next couple of days.
M: Two days later? But... you see, my teeth...I can’t bear them.
W: Yes, I see. Please wait a moment. I’ll call the doctor.
(After a minute.)
W: You’re so lucky. The doctor asks you to come here at around 8:30 tomorrow morning. Will that be all right?
M: Well, yes. But what time is the clinic open?
W: We start from 9:00 a.m. and close at 5:00 p.m. on weekdays. The doctor will look at your teeth before work.
M: Thanks. I’ll come here at 8:30 tomorrow morning. Goodbye.
W: Goodbye!
