The World's Worst Passenger

What the title says - The World's Worst Passenger

The world's worst passenger buys her ticket 10 minute before the train is due to leave the station, runs across the platform knocking everything down on her way, catches the train just in time, and gasps, 'thank you' to everyone in general and no one in particular.

Sort of like me, seeing this prompt and entering "The Writer's Cramp"  today.
