A gun is like a coupon that never expires!
A Florida woman attempted to use an online-only coupon to get one dollar off at her local Walmart. When her coupon was rejected, the woman became belligerent, warning Walmart employees—who at this point find nothing surprising—not to follow her to her car. She then retrieved her loaded Smith & Wesson .38 Special from the car and waved it around a bit. Eventually, she drove off and was pulled over by police. Obviously, this is exactly what our forefathers had in mind when they drafted the Second Amendment. The unconscionable tyranny of cashiers is why we fought the Revolutionary War, after all. As you'll recall from history class, the British refused to honor a coupon for buy-one-get-one-free haddock, and all hell broke loose.
