I hate people today. I especially hate hate hate people who don't have any grocery store etiquette-do you have to leave your cart in the middle of the aisle, then have the balls to shoot me a dirty look when I ask you to move it? Maybe I'll just start bumper carting.
Anyway, that's my pet peeve (along with drivers who don't use turn signals). What's yours? Silly, serious, whatever they are, let's hear them!
