U: Hello. I'm looking for a hotel on the north end of town with a 4 star rating.

S: I can assist you with finding a place to stay, but first, I can tell you we have no 4-star hotels on the north side of town in our database.

U: Nothing in the north, four star?  I need that and cheap with free parking.

S: Sorry, I don't have anything 4 star in that area.  Would you like to try another area?

U: I really need something in the north that has 4-stars. Can you double check? I would even take a guesthouse if there is one.

S: I have found a guesthouse, Worth House, that meets all your criteria (north, cheap, 4 stars, free parking).  Would you like help booking this guest house?

U: Does Worth House have comfortable beds?
S: Yes, the Worth House is capable of supplying comfortable beds to the majority of its guests, although some may not find the mattresses to be their liking.
