Please help me find a guesthouse to stay in that has free wifi. 
I can help with that. What area would you like to stay in?
I don't care. I want a 5 star rating though.
I would need an area to narrow the search for you. 
Any are would be fine. Can you just check if you have anything that's 5 star rated?
I do not have anything that meets that criteria.
How about one that is a 0 star?
I have two with a 0 star rating, one in the north and one in the centre.  Do you have a preference?
No, it doesn't matter. Thank you.
I recommend El Shaddai.  Can I get you information on it?

You are booked with reference number 9N3UAJNA.  Anything else I can help with?
