U: Hello, any interesting colleges in town?

S: I am showing 18 colleges. Is there a certain area of town you would like?

U: Not really.  Which do you think would be the most interesting to visit?

S: I would suggest Christ's college in the city centre or Corpus Christi college in the west.  Christ's college is free and Corpus Christi costs 2 pounds? Which do you want?

U: What is the postcode of Corpus Christi?

S: Their postcode is cb21rh. Can I assist you with anything else?

U: I am looking for a guesthouse to stay in.

S: I have 24 guesthouses.  Let's narrow it down a bit.  Do you have a price range?

U: I need something with free parking and a 4 star rating.

S: That cuts it down to 16. I can recommend the Acorn guest house, or do you have a pricerange or area of town you want to stay in?

U: Before I answer, can you tell me whether the hotel employs friendly staff?
S: The staff at the Acorn Guest House are very welcoming and smiley. Do you want that or do you want more information first?
