S: Certainly! What day are you traveling?

U: My meeting is on Wednesday.

S: Do you have a preferred arrival or departure time?

U: I would like to arrive by 19:30.

S: Train TR2379 departs at 17:16 and arrives at 18:35. Will this work for you or would you like an earlier time?

U: That's all I needed to know about the train. Thank you. I'm also looking for a moderately priced place to day with four stars.

S: which side would you like to be?

U: the area doesn't matter but make sure its a hotel and not a guesthouse including free wifi.

S: I'm unable to find anything that meets all of your criteria. Can we adjust your price range to find the appropriate accommodations?

U: how about one that is in the cheap price range

S: How about The Cambridge Belfry? It is cheap, has four stars, and has internet. Shall I make a booking for you?

U: Do they have beds that insure I will get great sleep?
S: According to the reviews I have on hand for that location, the beds there are comfortable and capable of giving you a decent night's sleep.  Sound good to you?
