So I was at the 42st Port Authority stop (A,C, E lines) around 4:30 PM today, for those non NYC members, it's a very busy station with many tourists and commuters, there was an old lady ahead of me, she had a rolling luggage cart and wanted me to swipe her thru with her card as she went thru the turnstile with her luggage, completely logical and understandable. I alreadly had my unlimited card in my hand, so I said, you know what, let me swipe you thru, I did, but then it didn't work for me at that...
