Say, "yeah, I hear ya! You like it more casual. Well, okay, I'm game."

PS. This is of course ridiculous, once they say the phrase you mentioned, they are not interested at all, but I think the comedy aspect/chance you'll annoy her makes this worthwhile. You can make it a lot stronger ('Oh I hear you, you little xxxxx' or 'you just want to be used like a kleenex, huh?' and so on) for exaggerated effect.
