Ugh... that's tough... sorry to hear.
But, in looking back, since nothing was said during and after it occurred, and then realized after the crowning, nothing will probably change the outcome in that tournament. It hurts, but, bringing it up to anyone wouldn't help-- if anything, it would probably backfire as sounding like a jealous looser.
The lesson learned was for the future. . . to call him on it.. . . but yeah, I agree with you. It's tough to be "that" guy.
Each year, we're in Team Play. One of a very few times, I made a call. My opponent was in the middle of a huge fairway bunker hitting his 2nd. There were some leaves and debris behind his ball but he casually picked it up and cleaned around them. I was right in front of him. Just before he hit his ball, I asked him if he would consider his ball in the bunker. He thought of it, and paused for a while and then he mumbled to himself, "sun uh by beach!" or something rather.
