Hello, I am looking for a place to stay in Cambridge.
I can help with that. Do you have an area of town, or a price range in mind?
I'm not picky about the area of town or the price, but I absolutely need free wifi!
Ok, almost all of the hotels have free wifi, do you have a star rating you would like?
I don't care.
There are 32 hotels that have free wifi. Do you have any preference of price range or area, or should I choose one for you?
I would like a guesthouse type but the price range is not as important.
How about the moderately priced Rosa's Bed and Breakfast? I also have 22 other entries, if you would prefer something else.
Rosa's Bed and Breakfast sounds fine.  Can you book it for 3 people arriving on Thursday for 5 nights?
Yes I most certainly can! I have booked you into the Rosa and your reference number is 06D0FC6L.
Yes I also need to book a train for 3 people on Thursday between Bishops Stortford and Cambridge arriving by 09:00.
I have a 7:29 that gets into Cambridge at 8:07. I booked three people on this train per your instructions. The total cost is 30.29 pounds and your reference is 9AR1CBJM.
Thank you very much for your help today.
It was my pleasure. Safe travels!
