Hi, This is Ben. I need a ride ASAP from Airport to University. Anything but a Lyft. 
I found a Uber ride for you from 'Airport' to 'Univeristy' for 44 credits
that could pick you up in 7 minutes. Should I book that for you?
uhm, ok
The ride is booked
Who is the driver? I do not want that guy Mark. He made me late last time and I missed an important meeting. 
The driver is Alex and his license plate is 313EA9. Your booking ID is 965
Actually my friend told me to meet her at Brewlab cafe at Craig and Center. Can you please change the destination to there?
I found a Taxi ride for you from 'Airport' to 'Craig and center' for 47 credits
that could pick you up in 9 minutes. Should I book that for you?
yes. That is perfect
Unfortunately that ride has been taken. But I have a Taxi with Alex as the driver. Should I book it for you?
ok, sounds good
The ride is booked. Anything else i can do for you?
