What happens if you are about to tee off from the wrong place and someone tells you?

If this happens, you pick up your ball and tee it up on the proper tee box, no penalty. However, if you or anyone in your group tee'd off from the wrong place they receive a two shot penalty and must correct their mistake (by teeing off from the proper tee box) before they commence the next hole. If they do not fix their mistake they are DQ'd.
