What is everyone doing, just standing motionless on the escalators? Are you following some esoteric social rule of which I am unaware? Is there a damn LAW!?

It's a moving stairway but still just a stairway; you can walk on it. JEEZ let's move along! This goes double for you bike-riding-wheat-grass-swilling-gym-zombies!!!
