Hello!
Hello, how can I help?
I'd like to schedule an appointment as soon as possible.
Could I have your name, please?
Alexis.
What doctor would you like to see?
Dr. Johnson! He's the kindest doctor in the whole world and has such good bedside manner.
What day of the week would you like to schedule the appointment for?
Can I do tomorrow? Also, I'd like to make an appointment for you daughter Angela to get vaccinated.
What time would you like to schedule for? I will also try to make an appointment for Angela at the same time.
Does 2 pm work?
Could you describe your symptoms, please?
I have a headache, dizziness, and muscle weakness for the past 2 days.
Unfortunately Dr. Johnson has no appointment available at 2 pm.
Okay, any time tomorrow works
Alright, Dr. Johnson is available at 5 pm. Can I book the appointment for you?
Yes, please. 
Great, your appointment with Dr. Johnson is booked for you!
Thank you, does that include Angela's appointment too?
I have also booked an appointment for Angela at 5 PM.
Great, thank you!
Thank you and goodbye.
