U: I want a hotel with free parking in the center of town.

S: Sure, I can help you with that.  Do you have a price preference?

U: Something moderate would be preferred.

S: I am sorry but there is nothing in the moderate price range.  Would you like another price range?

U: What about a moderate hotel located in the North?

S: I have found 9 hotels in north. Do you have any other preferences so we can narrow them down?

U: No other preferences.  Can you pick one and book it for 6 people for 3 nights starting Friday

S: I was able to book your party of 6 into Acorn Guest House, reference 1IJ5VMO1. Is there anything more today?

U: How have reviewers described their beds?
S: Some guests have said that the beds where so comfy that they slept like babies.  Other guests have said that their back hurt like crazy and the bed was of extremely poor quality.
