Can you navigate me to a 5 star hotel with free wifi please?
I was unable to find any hotels matching those requirements. 
Do you have a place with free wifi in the cheap range with a star of 4?
I've found 21 hotels that meet those criteria. The Allenbell is one. Should I book it?
What type of hotels are they?
The Allenbell is a guesthouse. Do you have any other specifications I can narrow your search by?
looking for something with 5 stars and free wifi
Sorry, but we've already established that there are no 5-star hotels available. I can provide you with some 4-star options.
Sorry, how silly of me. I want to stay at a hotel, not a guesthouse. A cheap 4 star with free wifi, please.
Okay, we've got the the cambridge belfry.  Shall I book you a room?
I don't need it booked just yet.  I just needed the info, thanks.
All right. Is there anything else I can do for you?
No, thank you for your patience.  I am all set now.  Bye.
Great! Have a wonderful day! Goodbye!
