W: Good morning, this is Dr. Aliens’ office.
M: Good morning, I’d like to make an appointment with Dr. Allen to have my teeth cleaned and checked. I’d like to have it done this week if possible.
W: I’ll see whether the doctor has time to see you this week. Have you been to see Dr. Allen before?
M: No, I’ve just moved to town and Dr. Allen was recommended by a friend of mine. My name is Edward Johnson.
W: The doctor has no free time this week, Mr. Johnson. If you are having trouble with your teeth, I’ll try to work you in, otherwise I can give you an appointment on Friday, the 22nd. Will that be all right?
M: I’m sorry, I’ll be working on the 22nd. I’m not having any trouble with my teeth but I had hoped to have the appointment this week because I won’t start work at my new job until next Monday.
W: How about Saturday, the 23rd, at 10 AM.
M: That will be fine. Thank you.
W: We’ll see you on the 23rd then, Mr. Johnson. Good bye.
M: Good bye.
