What do you do when your playing golf, and someone blows an airhorn?

What would you do if you were playing a round of golf, and someone that is hiding outside the course blows an airhorn when your are about to hit a shot? Also has anyone of you experience this situation, when your were about to hit a shot, and someone blows an airhorn, to distract you, and what did you do? What would you seriously do, if someone blows an airhorn when your about to hit your shot? As real golfers, what would you do? Chase them, then throw your club at them and get mad? Or rush up to the clubhouse, or find a marshal in the golf course, and report them, and they would take care of the rest. Well I think that is the right thing to do, that you have to report it to any employee of the golf course. What would you do, and what is the right thing to do?
