Hi, I'm Ben. I need to make an appointment for today.
What doctor would you like to see?
Dr. Alexis and I need it to be today (Monday).
At what time can you be at the clinic?
What ever time is open. 
Could you describe your symptoms, please?
Yes, I've had a cough and sore throat for two days now.
Alright, Dr. Alexis is available at 8 am. Can I book the appointment for you?
Yes please, is there anyway I could get my son John seen as well? He need to be vaccinated.
Great, your appointment with Dr. Alexis is booked for you. I will check for a time for your son.
Okay thanks.
There is a time slot available at 9am for your son. Is this okay to book for you?
That would be wonderful.
Great, both of your appointments have been for you! Is there anything else I can do for you?
That is all, thanks again.
Thank you and goodbye.
