U: I am looking for a guesthouse to stay at in the moderate price range.

S: How about the a and b guest house?

U: Does it have free parking?

S: No, it does not offer that. Would you like something that does?

U: Yes.  I need free parking, and I prefer the southern part of town.

S: ok, I have a couple that meet that criteria. Would you like 3 or 4 stars?

U: I have no preferences. You can just pick one. I'd like it for 7 people for 5 nights starting from saturday.

S: This is unavailable would you like to book a shorter stay or a different day?

U: How about 3 nights for the same day and number of people?

S: Great! You're booked for 3 nights at Bridge Guest House with reference number AH7L4RXZ. May I help with anything else?

U: Do they have helpful staff there?
S: The Bridge Guest House has several complaints about poor quality of staff. Would you like to look somewhere else?
