U: I'm looking for a hotel in the expensive price range. Internet is not necessary.

S: We have 5 hotels that meet your request.  Is there a specific area you'd like to stay in?

U: I need a place in the east, please.

S: That would be express by holiday inn cambridge. Would you like to book that?

U: Um, no thank you. I think that's all I need for today!

S: Thank you for using our service.  Have we met all of your needs?

U: No, actually I do need to book the Holiday Inn Cambridge as long as it has free wifi.

S: The holiday inn cambridge has internet but I do not have any information on whether or not it is wifi or free.

U: Are the rooms dirty there?
S: The reviews are mixed concerning the cleanliness of the rooms at the Express by Holiday Inn Cambridge as half the guest had less than perfect experiences.
