U: i need a hotel with wifi in the north part of town

S: I can help with that. What kind of price range do you have in mind?

U: I am open as far as price range, but I would love a 4 star place.

S: There doesn't appear to be a 4 star hotel with wifi in the north. Can I interest you in a lower star rating?

U: No, the hotel needs to have a 4 star rating. Can you please check your system again? Thanks

S: i am sorry. i have double checked and still do not find anything matching your criteria. would you like a different star rating?

U: Perhaps there is a guestroom?

S: No but would you like to try another location ?

U: Just something in the north, 4 star and free wifi?

S: Okay, there are 8 guesthouse listings fitting your requirements. What pricerange are you looking for, may I ask?

U: Do you have anything moderately priced? I need it for 6 people, for 3 nights, starting monday.

S: They're all moderately priced. I recommend the Avalon.

U: Does the Avalon have mattresses with good support for bad backs?
S: The Avalon hotel has very comfortable mattresses according to one guest, but another found them to be really bad.
