My brother and I ran to Costco this afternoon. I had this guy who was coming at me from the opposite direction for several isles. On the first isle I politely moved my cart to the side. For the next four isles however, he never made any effort to move. Not even an inch. My brother dared me to ram his cart on the next pass and I accepted the dare. Fortunatley for him, his wife dragged him to the center of the store.
