In the days after the hurricane, the lines were long at the grocery store, as most people didn't have power and could only buy a little bit of food at a time . . . and so when the woman in front of me started to panic because her credit card wouldn't swipe, I stepped forward and saved the day . . . I said: "Why don't you put your card in a plastic bag and then swipe it?" and both her and the cashier nodded their heads -- they had heard of this technique, but I am assuming that because they were so traumatized by Sandy that neither of them thought of the "bag method" . . . otherwise known as the Aiken biphase modulation scheme -- and so the cashier gave the desperate woman a grocery bag, and she encased her card in the grocery bag and then swiped it and BAM! . . . credit was granted and there was much rejoicing; when the woman thanked me, I humbly said, "No problem," but, of course, everyone in that grocery store knew that they were in the presence of a true hero.
