Hi, I'm Mark. I need an apointment with Dr. Johnson for today (Tuesday). I have had a runny nose, sneezing, and a lack of energy for two days. 
At what time can you be at the clinic?
Well, it is 8pm on Tuesday now, so I can be there at any time after now. I'd like an appointment as soon as possible. 
Alright, Dr. Johnson is available at 9 pm. Can I book the appointment for you?
That sounds great. I really want to feel better. This is the third cold I've had this month!
I'm sorry to hear that. I hope you feel better soon. 
Thank you. I'm sure I will. Dr. Johnson is great. Did you know he was in the Ollympics?
I did not know that. Interesting. 
Actually, while I have you, I'd like to get my son, John vaccinated. Can you make a second appointment at the same time?
Great, your appointment with Dr. Johnson is booked for you!
You got the appointment for both me and John?
I added it to the notes that you would be bringing John for vaccines to the same appointment. 
Okay great. So everything should be set for both of us? That is good. Hopefully the dr. will share more stories from his athletic days. 
Great, your appointment with Dr. Johnson is booked for you!
