U: I am looking for a 4 star guesthouse in Cambridge.

S: I have 18 results that match your request. To help narrow it down, what part of town would you like to stay in? Do you have a price range preference?

U: The hotel also needs to be cheap and have free wifi.

S: There are 7 hotels that meet that criteria. Do you have an area preference?

U: Do any of these 7 have free wifi?

S: They all have free wifi.

U: Any of them will do.  I'll book a room in whichever one you think is best.

S: The alexander bed and breakfast is in the center of town, would you like help with the booking?

U: That depends. Is the Alexander known for quiet rooms?
S: Customers have stated that the Alexander is noisy, customers have stated that the walls are thin and that there's a lot of traffic outside that the traffic noise makes the rooms loud.
