Do they need to say that ? Surely anyone hitting a ball on the course, if considered to be a caddy, disqualifies the player they are caddy to once they are classed as caddy. The rules surely forbid that, or you would have caddies hitting putts to get a feel for their player, etc.And I agree. The T of C could say that anyone playing on the course cannot be a caddie for a player in the competition. But that is unlikely for club events.
