New York transit

I told you about the surprising incident at Tom's restaurant. Here's another one about New York - but this is a good one.
Soon as we landed in New York, we took a subway from the airport to Jamaica. We purchased one metro card for $ 20 -which was the lowest denomination we could purchase at the vending machine as we did not have bills handy.
We did not realize then that you could swipe a card only once in half an hour. We kept swiping it again and again but the gate would just not let me out. Finally, a couple of security guards came to our help and managed to fool the machine and let us out. That was nice of them :)
But - our card with $15 balance wouldn't work any more. We thought we had lost the money and continued our trip but just before coming back, we found out that they might refund us with another card if we sent ours to New York transit. We did that for the heck of it - a couple of weeks back and 2 days back we got a cheque and a letter from them :)
I guess they sent us a cheque because we live in Minnesota and a metro card would be of no use to us. Isn't that cool!



Even though this is how things are supposed to be, I am still surprised because I still remember the times when me and my sister used to travel by PTC buses from school and the conductor would never give us back 5 paise change.
