I agree with the above except, I have been in scrambles where it is stated up front that if you decide to play out of a bunker the player who hit it in the bunker must play first (i.e where it lies) then the others can rake and place their ball before hitting.

I also suppose that the event could have special rules concerning that the players ball you select must play the shot down and can not place it, have not been in such event but that would seem to mandate him hitting first.
