My Dad came down to visit this weekend and we played a round Sunday morning. I only get to see my Dad 2-3 times a year so everytime we get together we make sure to get a round in because we both really enjoy playing with each other and really look forward to it.
A buddy of mine came up and played with us and he asked if it would be OK if he brought along his assistant to make it a 4 some. No problem I told him, thinking it would be someone our age and ability level. I was a bit shocked when he showed up with a kid that couldn't have been more than 21 at the most, but still, no problem.
This kid could hit the ball a mile and had some real natural ability. Unfortunately, he had the manners of a 5 year old.
Here's just a few of the things he did:
If he hit a bad shot he would throw his club 10-20 yards down the fairway or back at the cart. I watched him hit one to about 20 feet from the pin and then throw his club because apparently that wasn't good enough for him.
He never raked one bunker he hit out of. In fact, he asked me why I was raking bunkers after my shots and said "Whoever was in there before you didn't do it so why should you?"
He hit one in the water on his second shot from the fairway, threw his club down the fairway and then walked down the left side to hit another from where it went in. I was setting up for my second shot and he walks right across my shot line about 60 yards away. I then procede to pull it left because I didn't see him out in the fairway until I swung.
He stood behind my Dad, on his line, as Dad was about to putt, several times. Finally my Dad told him, "If you are going to stand there, don't move around while I putt".
He also kept trying his putts again while we were still putting out. By this I mean that if he missed his first putt, he would tap in and then throw his ball back to where he originally hit it then putt it again while we were still putting out. THIS DROVE ME CRAZY!!!
I was on a slow burn after he walked across my shot but Dad said to just let it go and don't let it ruin our round so I never said anything to him since I'll probably never see the kid again much less play a round with him. I figured anything we would have said would have went in one ear and out the other anyways.
I had been looking forward to playing with my Dad for 3-4 months so we did our best not to let it bother us but we both agreed the kid needed a lesson on course etiquette as well as about 5 years more maturity.

What would you have done??
