If you play golf you are going to be hit into, usually innocently. The old man in the OP is a complete idiot. Losing your sh/t because some guys ball ROLLS past you 300+ yards from the tee box makes you the kind of golfer that the sport would do well to lose. I've been hit into so many times I would have had a stroke by now if I lost my temper like that each time. It's usually younger, more impatient guys that are the offenders.
