Hi, I'm looking for a 4-star hotel with free wifi.
Sure thing. I have two options for you, and they are both guesthouses. One in the east, and one in the north. Do you have a preference? 
Are either of those two cheap? 
No I am sorry, they are both in the moderate price range.  Would you like to book one of them?
Any one will do as long as it has a 4-star rating with free wifi and is cheap. 
There are no 4-star places that are cheap and have free wifi. Perhaps something not as fancy, or in a higher price range? 
I'm not sure.  I really needed those specifications.
I apologize, we have several options. The alexander bed and breakfast is a cheap four star guesthouse, in the north area, with wifi. Would you care to reserve a room?
Yes, let's book it for 3 nights from Wednesday. There will be 5 of us.
Okay, I've made your reservation. The reference number is 525A3U0N. What else can I help you with today?
You've taken care of everything. Thank you.
Thank you have a good day.
