Hi, I need my usual ride to Airport this is Angela. Pick me up at University. 
I found a Lyft ride for you from 'University' to 'Airport' for 46 credits
that could pick you up in 27 minutes. Should I book that for you?
who is the driver? I do not want Alex
Your driver will be Mark.
Ok, book it please
Your ride has been booked
please cancel that. They have scooters right across the street. I will grab one of those. 
Your ride allowed changes. We will cancel the ride. Is there anything else I can do for you?
