1. People who swing one or more arms wildly when walking down a crowded city street. Not a day goes by in which I am not smacked, or near-smacked, by some idiot (usually a moron wearing headphones, oblivious to anyone or anything else around them. That's for another day though) flailing their arm as they walk, This is not necessary, jerks. The human body is quite capable of moving forward and staying balanced with a gentle back and forth motion of the arm. Cripes, at the very least, pay attention to things around you

1. People who either a) stand on the escalator refusing to walk up (with a subset of people who stand on the left, this really irritates me) or b) people who walk part-way up the escalator and then, with a few feet to go stop walking . Why stop when you are 2/3 of the way to the top? What are they thinking? This might be worse than not walking up at all. Don't get me started.
