Have we got a new stress-related malady called 'Checkout Rage' ? Is it really a wide spread phenomena? Are people all around the nation, overburdened with busy schedules and heavy senses of entitlement, having fist fights over expired coupons? Are you risking your life taking 11 items into the "10 items or less" checkout line?
Or are there just professional assholes (also known as "flaming asshats") roaming around without their wardens making for good news copy?
