I need to take a train from Norwich, leaving after 21:15.
Where would you like to go to?
I would like to go to Ely please.
I don't have any listings for trains leaving Norwich and arriving in Ely. Would you like to try a different departure station?
I meant Cambridge please. I would like to arrive in Cambridge on Monday after 21:15.
Ok I will book that for you and get you a confirmation number
I don't need anything booked.  I just need to get the arrival time, travel time and price of a train from norwich to cambridge leaving after 21:15.
There are trains arriving at 22:35, 23:35 and 24:35. They are 17.60 pounds and 79 minutes each.
Great, thanks! I'm also looking for a 4 star hotel in the north. Can you please help with that? 
There are several that meet your criteria. Is there a price range you are interested in?
I would like to keep it in the moderate range, please.
I see 7 options. They are all guesthouses. Do you have preferences for internet and parking?
I do not have a preference on those things.
Shall I try to start and book you into one?
Please book it and provide the reference number.
How many nights will you be staying?
Please book the hotel for 4 people and 2 nights.  Thank you.
What day will you be arriving?
the same day... monday please.
I apologize, some of our new workers have phobias of the booking system, I booked you at Acorn guest house, the reference number is 04CSEO7Q any other questions?
That's all I need for today.  Thanks for your help!
I'm happy to help, and I hope you enjoy your stay!
