Over the last few years of subway commuting I've mastered the passive-aggressive shoulder and foot strikes. Last year my boss kicked a woman's roller backpack out of his way because she was obstructing a crosswalk.
People that walk directly at me on a sidewalk, ect. I could just stay my course, and destroy them in most cases, but I always feel obligated to move out of the way because it doesn't feel right to bodycheck a civilian. One of these days I'm going to lose my composure and start lighting people up with bonecrushing open ice hits
