What is Soneji's state of mind when he arrives at Penn Station?

Soneji arrives at Penn Station and knows that he will be "out-of-his-head furious" once he gets upstairs to the main terminal. His anger is fueled by the sight of the commuters and the surly porter, and he becomes even more aggressive when he sees his first victim, a businessman in a gray-striped suit who reminds him of his father.
