My name is Ben.
Hello, how can I help?
I need a ride to University.
OK, and where are you departing from?
Airport
I found a Taxi ride for you from 'airport' to 'university' for 28 credits
that could pick you up in 29 minutes. Should I book that for you?
In a Toyota if possible. And I need to change my destination to 5th and Main.
I found a Uber ride for you from 'airport' to '5th and main' for 39 credits
that could pick you up in 20 minutes. Should I book that for you?
And please not Dave for a driver he got us lost last time. And can I have a BMW instead?
I found a Lyft ride for you from 'airport' to '5th and main' for 27 credits
that could pick you up in 30 minutes. Should I book that for you?
Yes, please.
Great! I've booked your ride, ID number 817, license plate 031 NGA
Thank you so much. 
Is there anything else that I can do for you?
No. Thanks.  I'm done. Have a good day.
Goodbye. Enjoy your ride!
