Its not the officials responsibility to tell the player! if a player is in doubt he then can ask the official. Rules officials do not say oh by the way theres hazards on this hole just to remind you and here's your options its the players responsibility the same when you go to school, play golf, play poker, go to jail everything in life the rules are laid out in simple english and here's the great thing if you dont know you can ask the 100 rules officials on the 18th hole just like Bubba Watson did who didn't know his options.
