Things that PISS me off

Cutting in line! It's one of those socially obnoxious, entitlement-minded things that some people do that make me crazy. And rarely is it really worth making a big stink over (I mean, do I really want to throw a hissy fit in the middle of the company cafeteria?) But instead I am sent away from the experience seething with resentment and rolling my eyes & muttering in frustration. People suck.
