For those that play, a cough, laugh, sudden noise can disrupt a swing - badly. Doesn't matter how focused one is, even putting a club back in the bag noisily, can cause problems. Was following a Buckeye player at Pebble, and got a glare when I moved, (was greenside with the hole between he and me), during his putting stroke. Golf is not like football/baseball/basketball, where fans have the right (?) to yell and scream at the players. Do this at the Masters, and you'll be escorted off the course. Fan is short for fanatic, and some of us knuckleheads believe that paying dollars for admission believe that gives us right to vent our opinions (loudly, and often crudely) about a player or a play. The key to Script's post is "after the ball is hit", certainly not during. So, I don't complain about Rory yelling 'shut up' to a 'fan', and applaud him for not adding an epithet to his comment. He'd probably get fined for doing so.
