My old man told me you can always pick out the asshole in the bar as soon as you walk in: loud, obnoxious, one too many Jack and Cokes, tryng to pick a fight with any stranger, barmaid, drinking buddy... And if you think everybody in the place is an asshole looking for a fight, it's time to call it a night, because the asshole is sitting on your barstool.
Funny how these new guys think everyone else here is the asshole looking for a fight.
