Some of these make me appreciate my playing partners a lot more.
- People that don't fix their ball marks are very annoying. I fix 4 per hole on average (except for tough par 3's). I'm generally not playing with these people though.
- "Telling a story on the tee box guy". No one wants to hear about your new fence or whatever, we're trying to tee off.
- Looking for balls forever. Dude, it went deep, we all saw it. Take your stroke and drop one already....
