Little stuff that can piss you off....

When, in the grocery store, I only have 3 items and i head for the "express" lane, and just as I get there some mathematically challenged a-hole beats me to the line, with a cart with 20 or 25 items, when the sign clearly states "12 items or less". I've already asked someone if math was a problem for them in school, only to have them look at me quizzically, and I state that they can't count to 12 properly. Nearly got into a fight or 2 cause of my mouth.

I've done that at Walmart. Have folks coming in the exit while I'm trying to leave and look at me like I'm in the way, I'll look up and say really loud: "EXIT! what's that mean?" Then usually say something along the lines of being illiterate. I've had a couple of folks try to call me out on it to try to save face. They usually walkaway looking even more like idiots when I stand there and define what "exit" means, how they obviously can't read or understand the definition and how inconsiderate they are.
