You will react one of two ways, either "wow, look at all that money she is saving" or "are you kidding me, she should do this when all the check-outs are open! Somebody get me a manager, I'm not waiting behind this psycho shopper!" I know this because, it happened to me when I went to check out at the local Wal-Mart Super Center. I was struck behind an "extreme coupon shopper" who by the way saved about $330.00, and the couple behind me who flew into a rage and was demanding to see a manager. I had never seen extreme couponing in real life before.
