I'm not sure, but I had a similar experience today on the golf course. There was a slow twosome on the first hole and three teenagers teeing up. The last one hit a decent drive that almost hit the twosome and didn't yell "Fore" (he should have waited anyway). I asked the threesome if I could play through and they let me. As I was walking to my ball, I hear the teen that almost hit the twosome yelling at the guy (from the teebox) because the guy picked up his ball and threw it part of the way back to the teebox. The kid then rode up to the twosome in his cart to tell the guy off (that's what it looked like) and I thought the guy was going to smack the kid. He walked up to the kid and was in his face yelling at him. Fortunately nothing happened, but I did bogey the hole and I blame that damn kid.
