I need to book a train that departs after 14:30 from Broxbourne please. 
Where will you be traveling to? I have multiple options for trains leaving after 14:30 from Broxbourne
I need a train to Cambridge, please.
And what day are you traveling?
I'll be leaving Broxbourne Tuesday.
How many tickets?
I don't need to book right now. Could you just give me the train ID.  I'll need one that leaves after 14:30 Tuesday.
The first available train on Tuesday leaves at 14:32. The train id is TR9417. Is there anything else I can help you with?
Yes, Im looking for a guesthouse that has free wifi and has 4 stars.
There are quite a few guest houses in Cambridge that would meet your needs. Do you have a preferred price range or area of town? 
No preference on either. Can you recommend me a place and can I get a postcode for that guesthouse? 
The warkworth house is a great choice for you, should we book a room? The postcode is cb11ee.
Yes, that sounds great.
How long will your stay be and when will it begin?
I'm not sure, actually. Just doing some research. Could you tell me what the price range is on the Warkworth?
It appears to be moderate.  Is that ok?
Yes that is fine.
OK, it seems to have 4 stars and offers both free internet and free parking.  Is there any other information I could get for you?
No thank you. That is it.
Okay, glad I could be of assistance.
