if you could read my mind...

I just heard a commercial on the radio for some psychic that ended with, "Remember, if your reading is not the best you've ever had, it's free!" I think that's a poor choice of words. Maybe, "if your reading is not the most accurate you've ever had." Because if the psychic told me that my entire family was going to die in a fiery car crash, it might be spot on, but I don't know that I'd call it the best.
