Hi. I need a train leaving from Cambridge anytime after 21:30.
Where do you want to go?
I want to go to Kings Lynn on Wednesday.
I have train TR2182 departing Wednesday at 22:11 and arriving in Kings Lynn at 22:58. Would that work for you?
Yes that sounds perfect, I will need 3 tickets and a reference number please. 
I was able to book you 3 tickets for that train. Your reference number is NYP3RNM4. Is there anything else I can help you with?
I am also looking for a place to stay, preferably a guesthouse that includes free parking.
There are 21 guesthouses that offer free parking, did you have any other requirements?
Is it also in the cheap price range? Does it include free wifi?
I have 9 entries meeting all 3 requirements, are you looking for a certain part of the city?
No - could you please choose one for me? I don't like to stress out too much about travel arrangements.
Sure. The Alexander bed and breakfast is in the centre, and their phone number is 01223525725. Should I book you a room? 
Yes, thank you.
I will need some more information to book a room, what day will you arrive, for how many people and how many nights?
I will be arriving Wednesday. We will need a room for 4 people.
Ok great I will book you a room for 4 people. How many nights would you like?
Let's just do one night for now. Can I cancel the reservation if I decide I don't need it?
You will have to contact the hotel directly to do that, do you still want to book the room?
No, thank you.  I am not ready to reserve quite yet.  Could you just tell me the postcode for The Alexander Bed and Breakfast?
The postcode is cb12de. Is there anything else I can help you with?
I would like to book the room and get the reference number please.
Ok. I am trying to book the hotel for 4 people for 1 night. You wanted the hotel for Wednesday night, right?
Actually I would just like the postcode and telephone number.
Sure.  The postcode is cb12de and the phone number is 01223525725.  Is there anything else I can help you with today?
No, that should do it, thanks!
We're happy to be of service. Enjoy your stay in Cambridge!
