I need a train departing from cambridge on friday.
I'd be happy to help. Where are you leaving from?
I am leaving Cambridge and need to go to Broxbourne on Friday.
There are 19 trains for Friday that fit your needs, would you like to narrow that down with a time you would like to depart?
I need to arrive by 18:15 please.
First one arrives at 10:01, how many tickets please?
Just one please. I also need a place to stay with 0 stars and an expensive price.
Okay your reference number is PLUBRYFC.  I'm sorry but we don't have any expensive hotels with 0 stars. Do you have any other preferences?
I suppose 1 star would also be acceptable. 
I'm sorry but we don't have any expensive hotels with 1 stars, either. Do you have any other preferences? 
Okay, how about one that is in the cheap price range, instead?
City Center B&B and El Shaddai are cheap guesthouses with 0 stars.
Is that in the north area of town?  
City centre is located in the north and el shaddai is located in the centre. 
Can I get their postcode and addresses and whether or not they free parking? Thank you.
Their address is 41 warkworth street, cb11eg. They do have free parking, can I make you a reservation?
No thank you, that is all the information I needed. Goodbye!
You're welcome, have a great day.
