I am planning my trip to Cambridge and need a train leaving Peterborough after 21:45. 
The first train leaves at 21:48.
That won't work for me. When does the next one leave on Tuesday?
I have one leaving at 22:19. Would you like to book it?
Yes that time works. Please book it. What is the train ID?
The train ID is TR8054. May i have your details (Name, Phone number, ID, email) so i can go ahead and make the booking for you.
I don't feel comfortable giving that to you. I'll book on my own. Can you just give me info on a place to stay?
Certainly. What area of town would you like to stay in?
I need a room. Do not need wifi or parking. 
Okay, I have the alpha-milton guest house in the north area.  Will that work for you?
Yes and Can you book it for me and get a reference number ?
On what day will you be checking in, for how long, and for how many people?
