I need information for a train leaving on friday after 15:15.
I'll be happy to help with that. Can you tell me your departure and destination cities please?
I am leaving from Cambridge and going to Bishops Stortford.
There is a train leaving at 15:29.
Perfect, can we book that for 2 people, and I will need the reference number.
I have made those reservations and your reference number is  5EVEW0AE.
Where do I collect my ticket?
You will get that from the station.
Great, thanks! Can you please also recommend an expensive place to stay with free parking?
Sure, the Lensfield hotel is within your price range and has free parking. The number is 01223355017 and post code is cb21en. Have a great day.
I wasn't done yet, but thanks I will have a great day. Now, can you tell me if that hotel is in the north? 
sorry. it is in the south.
Okay. So how about one in the north then, because that's what I want. If not, then try the centre. And don't try to book without my permission again please.
There are no hotels in the expensive range in the north.
