You could be frank: "I visited you previously, and wasn't impressed, therefore no cancellation fee".
Or do extensive research. This forum helps very much.
Funny enough, a WG I contacted some time back actually reduced her rates after moving from a venue to private setting. Her service wasn't that grand though, so it could have been the reason she dropped prices, after some not so good reviews on here.
I also suspect that some girls have different prices depending on how they perceive you, or which site/ad you saw them. After all, nobody can really stop them from increasing prices at random.
