It happens to all New Yorkers.
You're running late for work. You swipe your Metrocard at the subway station only to see the words "INSUFFICIENT FARE" staring back at you. Damn it.
You run over to the Metrocard machine to refill your card. If you can do it fast enough, you might just catch that next train, get to work on time, and everything will be fine.
But wait, what is this? Some noob tourist in front of you is fumbling around on the MetroCard machine. He or she is taking forever. Damn it!
How difficult is it to press a few buttons? How hard is it to stick a Metrocard in that little slot? Why do this person have so many Metrocards?! "Who are you?" you hiss.
You have never felt this much rage towards another person in your life. He or she is everything that is wrong with the world.
