Time to go postal.
Let me explain something to you, Dave. There are two kinds of angry people in this world: explosive and implosive. Explosive is the kind of individual you see screaming at the cashier for not taking their coupons. Implosive is the cashier who remains quiet day after day and finally shoots everyone in the store. You're the cashier.
