I have been high holed two times that I can recall, both times by fly fishermen and based on the reaction I received, I may have high holed someone once.
High Holed #1 - On Father's Day at a creek I used to fish regularly with the entire stream OPEN, a guy slipped in about 30 feet above me as I was moving upstream. I got out of the creek rather sloppily and from a bridge above the stream, I threw rocks in the pool he was fishing while wishing him a "Happy Father's Day."
High Holed #2 - On another old favorite FFO stream I guy did a similar thing as I was moving and casting upstream. I waded out of the water like an elephant right in front of him...
High Holer #1 - I was getting ready to fish the Letort and encountered a local who I knew with a somewhat dubious reputation amongst other locals. He asked me if I was fishing up or down and I said "up" and he proceeded to walk WAY downstream as I was surveying the stream.
Just before I started moving up, I spotted a riser about 10 feet below me. I snuck around behind the fish and not seeing the other guy, I made a few casts and caught maybe an 7" dink. Right about that time the other guy was right behind me, admonishing me because I didn't move upstream or upstream far enough...
#1 - If he wanted to fish the spot where I caught the dink and said so when we first met, I would have been more than happy to move up past the next bend.
#2 - When someone moves 100+ yards below me, do I have to move another 100+ yards above them?
#3 - I caught a dink, not some 20" trophy...
Which brings me to two spin fisherman encounters; one involving a spin fisherman I encountered who volunteered to move WAY, WAY above me when we bumped into each other on a local stream. I never saw him again that day...
The other was a day when I went to the Delaware to fish for shad with spinning tackle. The spot where I was fishing was popular with the non-wading crowd. When I got down to the river I was dismayed to see the bank lined with fishermen.
I was getting ready to leave when a guy yelled out to me, "Don't go, you can fit in next to me." Then the guys around him moved a bit to either side and I slipped in between.
No arguments, no complaining, miraculously no crossed lines and when someone hooked up, everybody else reeled in their lines so the other angler could play their fish.
Imagine that...
