They've already been making us pay 10 cents for a bag for a few years now, anyway. Walmart recently started doing it, too. What pissed me off was that when they started charging, I was not informed, not even at checkout, and was just charged the fee.
You can just steal a plastic bag from Walmart though by doing self-checkout, saying NO when the dumb machine asks you if you want to pay 10 cents for a bag, then take one anyway. I stole one and got away with it. I guess it makes up for the one they charged me for.
