I put my cart up.
That's right, and as I was walking back I thought to myself "I just walked two measley aisles over and I feel accomplished for today. Why? Because so many of these schmucks didnt. That guy over there turned the cart over on the little island thingie so it wouldnt roll. That was nice, but I still did one better."
The easy way to feeling smug, is this wrong? =P
