One of my friends is an ump for these all-day baseball tourneys. The crap that he takes from parents (that are almost certainly some level of inebriated) is incredible, and I'm surprised that he has that level of restraint.
Some parents deserve to get embarrassed in front of their kids with a fist to the gut. I'm just saying.
No issues with having fun and drinking some beers during these all day tourneys.
But when you turn into a belligerent ass, you deserve to get knocked out.
