U: I'm looking for a train that leaves on monday after 16:15.  Any suggestions?

S: Where are you departing from and what is your destination?

U: I'm leaving Cambridge and headed to Ely.

S: There is a train to Ely that leaves at 17:50 on Monday. Would you like me to book it?

U: No, I just need the train ID and arrival time.

S: Sure the train id is TR4294 and the arrival time is 18:07.

U: I am also looking for a guesthouse with a rating of 4 stars.

S: I have several guesthouses with 4 star ratings. Is there a particular area you'd like to be in?

U: It does not matter but I  would like free parking.

S: What price range would you like?

U: Price range is not important, just the four stars.

S: What area of town would you like?

U: As long as it has free parking, that's all I really need. Can you recommend one and tell me a little about it?

S: I have 5 guesthouses with free parking. I recommend the Acorn Guest House in 154 Chesterton Road, postcode cb41da.

U: Is there strong water pressure in the showers there?
S: No, unfortunately water pressure isn't one of the highlights of staying at the Acorn Guest House as theirs is pretty weak.
