If you knock over a security delivering coffee to the boss

You find by kicking as hard as you can with your legs and then jumping into the chair you can get insane speeds, sliding the rolling chair down the hall, and better still, the thing has amazing handling, it goes pretty much in a perfect straight line! The best place to do this is a long hall that quarters the story off into quarter sections. This is a four way hall leading to windows of the city below. Your luck holds out for twenty minutes, then while zooming past the intersection in the ultra-quiet chair you collide with a huge warty and troll like security guard on her way to bring the boss his coffee. She holds onto the steaming cup like her life depends on it and somehow manages not to spill it in her tumble.
