Not quite as extreme as you guys.....
But this one year my house was having a super bowl party (the year between seattle and san fran when the power went out) and we filled a cart jam packed full of bacon cheese, burgers, nachos etc and got to the lines and noticed every fucking other person thought of buying things for super bowl at this time. One of my friends was by the exit looking at sushi and we just casually walked out. No beepers went off and they were way too busy to notice this. We must have got away with upwards of $300 of stuff. It was a good super bowl.
