Can you find me a cheap guesthouse to stay at?
We have nine cheap guest houses. All offer free internet and free parking. Some have 0 star ratings and others have 4 stars. What sounds good to you?
Great, I want one with 4 Stars.
There are several that meet that criteria. I can recommend the Autumn House in the East of the city.
Sure. Please book a reservation for two people, Saturday, two nights. 
Autumn House is full.  Can I try to reserve one of the other ones for you?
Yes, try another place as long as it is still in the cheap price range.
How about allenbell? Your reference number is 2SUPQQPL.

Thank you and goodbye.
