I went to barnes & noble and i was looking at some books, there was a guy next to me who was doing the same. He was backed against the opposite shelf. So my choices were to go all the way around to get to the other side, or just walk right in front of him. I walked in front of him and he sighs and gives me a dirty look. So was this guy an ass or is their some rule where you shouldnt walk in front of people for less than a second?
