Hello. 
Hello, how can I help?
My name is John. 
Ok, how can I help today?
I need a quick ride to Hospital from University.
I found a Uber ride for you from 'Hospital' to 'University' for 38 credits
that could pick you up in 13 minutes. Should I book that for you?
I'd like to ride in a Tesla if possible.
Ok, I have booked you a ride with licence plate '432 LSA'. Your booking ID is '529'.
Wait sorry. I see a scooter rental stand across the street, I'll just take that. Thanks anyway.
Ok canceled, is there anything else that I can do for you?
No. Thanks again. Have a good day.
Goodbye. Enjoy your ride!
