A couple of months ago I was grocery shopping at the local Walmart marketplace, as I was walking down the main aisle this guy just pushes his cart/buggy in front of me blocking my way. He was looking directly at me with look like what was I going to do about his power over me. So I turned left and went down the aisle that was there and left him standing there. I was wondering how many times he has done that to other people and what kind of reaction he was expecting.
