It's amazing how much rage people have inside them. It nearly happened to my golfing group once. Which I guess isn't bad for about 40 years worth of golf.
Golf on a holiday Friday (5 1/4 hr round). High School kids behind us. 3 out of the first 5 holes we were hit into while waiting to hit our shots, including a near hit to the head the third time. An attempt to have a civil conversation with one young man went horribly wrong when first he ignored us and then he got into a rage and threatened us, club in hand, when we insisted they stop hitting into us. I really thought it was going to be bad for a minute but we got things settled down and got back in our carts.
We ended up calling the club and they had a marshall come out and ride shotgun with them the entire rest of the round. The marshall came up to talk with us and told us the kid who threatened us should know better as he worked at a private golf club. The funny thing was, the kid worked for an old high school classmate and friend of mine. Later when I had a chance to talk to the kid, I couldn't resist asking the kid how he liked working for Jacky. The kid looks at me funny and asks me how I know Jacky. Oh, Jacky and I are old friends and former high school classmates. Suddenly mister tough guy looked like a scared little puppy.
Hope he learned a lesson.
