Wow that is a terrible example of an AP'er.
I think it is a terrible example of behavior in general at these sort of events. I've seen not-so-relaxed behavior when just observing as well. And I haven't even run into the guy who has been having collimation issues all night and trying to tweak it yet.
If a guy is letting themselves be wound up over something, then that is a possible problem in the making. It doesn't really matter what it is.
