U: I want to find an expensive 4 star hotel.

S: I have 2 expensive 4 star hotels, one in the west and one in the centre of town. Do you have a preference to area?

U: Do you have one in the south that includes free parking?

S: I'm sorry, no, none in the south.

U: Okay, I'd really like to stay on the south end of town so is there one in the cheap price range instead?

S: i don't have any hotels in the south part of town.

U: Well are there any cheap hotels anywhere in town?

S: There is a cheap hotel with 4 stars on the west side of town. If you could restate your exact preferences I can try searching again.

U: Sure.  Look for a cheap hotel, 4 stars, in the south.  Free parking also.

S: There are no hotels that meet your criteria in the south.  There is one cheap 4 star guesthouse with parking in the south. Does that work?

U: Can we start over? I think there is a bit of confusion. I need a hotel with four stars, in the south, and free parking

S: There is nothing in the expensive range, there is a choice of one cheap or one moderate 4 star guesthouse in the south with parking. Would either of these be OK?

U: Cheap is fine. Please book for Friday, 3 nights, 3 people.

S: It is not open then, how about a shorter stay?

U: I can book for 1 night instead.

S: Very good.  You are set for 1 night at Rosa's.  The reference number is 8QUJMPP7.  Is there anything else I can help with?

U: Has the room been thorougly cleaned?
S: One reviewer raved about the exceptional job performed by the housekeeping staff. Is there anything else I can help you with?
