I need a taxi from london kings cross train station to the gonville hotel.
Tell the customer what time the train departs from London kings cross train, and possible arrival time to gonville hotel.
Um what? I need to arrive by 23:00. Can you help or not?
I'm sorry about that.  I have booked you a black audi arriving at the hotel by 23:00.  The contact number is 07582132009.

That's okay, thanks so much for your help. Have a good day now, bye!
You are welcome.  Bye.
