I need to get out of Cambridge quick! Can you find me a train for tomorrow, Tuesday? 
I can help you. What is your destination?
I would like to arrive to Cambridge from Broxbourne and would like to leave after 15:45.
A train is leaving Broxbourne at 16:32, arriving Cambridge at 17:32. Shall I book a seat for you?
Yes. I actually need 3 seats
The booking was successful.  Your reference number is Y25Y52KM.
Can you find me a place to stay in the centre. I don't need internet.
I'm sorry, I'm not finding any matches, would you like to try something else?
No thank you I will call back
Ok. Is there anything else you need? Information about attractions or a restaurant reservation perhaps?
Well, I do need a place to stay. How about one with free wifi in the centre of town?
Do you mind if it's a guest house? The Alexander Bed and Breakfast is an inexpensive 4 star guesthouse offering both free wifi and free parking.
No, I really would like a hotel in the centre with free parking and it can have wifi. 
All of the 4 star hotels in the area are expensive. Would you like me to drop the star rating for you, or are you okay with it being expensive?
If there are no hotels with free parking in the centre, how about one with free wifi?
The university arms hotel sounds perfect: hotel in the centre of town, expensive, 4 stars, with internet and parking. Can I book a reservation for you?
I guess that will work book for 2 please
OK. What day will you want to check in, and for how many nights?
I would like to check in on Tuesday please. And I want to stay for one night.
OK, you're all set. Is there anything else I can do for you?
No thanks. That would be all. I appreciate your help. Take care. Bye. 
Did you need a reference number or anything like that?
No thanks. I forgot I should wait to book until I am sure how many people we will have. Thanks though. Good night!
Okay, have a great day!
