U: I am leaving Cambridge and need to go to Broxbourne on Friday.

S: 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?

U: I need to arrive by 18:15 please.

S: First one arrives at 10:01, how many tickets please?

U: Just one please. I also need a place to stay with 0 stars and an expensive price.

S: 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?

U: I suppose 1 star would also be acceptable.

S: I'm sorry but we don't have any expensive hotels with 1 stars, either. Do you have any other preferences?

U: Okay, how about one that is in the cheap price range, instead?

S: City Center B&B and El Shaddai are cheap guesthouses with 0 stars.

U: Which one has the yummiest breakfast?
