I was sorely tempted to go Masshole on this guy, since despite lacking an accent due to being from the Western part of the state I sure as hell am. In fact, considering I have an ancestor (on my mom's side, no less) who was here nearly 400 years ago back when it was a colony and has a frickin' statue at the State House (yes really) my ties to Mass probably go back further than this jerk's. And my dad's family's been here since the mid 1800s.
But I resisted, since we're not supposed to sass the customers, no matter how much it's deserved. And by my rules, you just do not treat people the way that guy did, especially when they're trying to help you.
