It does annoy me quite a bit that people who call infractions are seen as jerks. Even in a less significant circumstance, such as a weekly league, i dont make it a big deal but if someone foot faults slightly, afterwards ill let them know. Not as a warning, but so they pay attention next time. Even in my effort to try and 'keep the mood light' for what amounts to a beer round thats barely a competetive thing, the response is generally pretty negative.
You almost automatically become 'that guy'.
Its hillarious to me some onthe bs that comes out of dg'ers mouths when they are penalized. Its usually not a statement defending their action as legal, its usually something along the lines of, "well, you havent been calling that when so-and-so did it" or "oh, i didnt realize we were playing with a professional" lol, its laughable.
