I dont want wifi, just somewhere with four stars. 
All of the 4 star hotels I have listed have wifi. Is that okay or would you like me to look for a hotel with a different star rating?
I guess it's OK if they have it, as long as they won't charge me for not using it. But 4-star accommodations are a must.
I have two 4-star hotels on the west side and one in city centre. Do you have a location preference?
Are there any in the South side of the city?
I have nothing in the south that matched your criteria, only west and centre. 
How about a place in any area with free wifi.
Okay I have the Cambridge Belfry which is a 4 star cheap hotel in the west part of the city. Would you like for me to book it for you?
Yes, please. 
For how many nights and how many people will be staying?
I need it for 7 people for 4 nights staring from Tuesday please.
I was unable to book that, would you like me to try something else?
Yes please and in the same price range.
Okay I was able to book you into the Marriott Hotel and your reference number is CQE0WWXH.
Thank you so much for your help.
Will you be needing anything else today?
Nope. You have been so helpful. Thank you!
