Living in NYC for past 7 years, I am proud to say that I’m a professional MTA card swiper. When my friends from out of town were visiting the city, I did not realize how much difficulties they were having at swiping their metro card. They became more anxious when they realized that there is a line of angry commuters waiting behind them. Swiping a metro card is like playing “Mary had a little Lamb,” on a piano with your eyes closed. You know exactly how the melody goes, but if you get the fingering/notes wrong, you have to start from the beginning. The same goes with the metro card. You know exactly how to swipe, but if you swipe it too slow or too fast, you will never get through.
