I have a friend who attended Augusta something like five years ago. At the time, the friend was a shy 19 year old and a scratch golfer. He idolized the pros.
As he walked by the driving range, he saw Vijay Singh playing shots off the front slope of the driving range from the rough with his three iron. Every shot was going high and landing soft right at the flag 225 yards away (these guys are ridiculously good).
My friend watched this display for several minutes and then said, “Hey Vijay, great shooting.” Vijay turned around and said, “No shit, did you see the name on the fucking bag?”
Ah, the gentleman's game. Remember that the next time someone tells you that spectators have to be respectful during play.
