I ran to get the train, but had no metrocard juice. Went to the machine, but someone had jammed a metrocard into the credit card spot on all the machines in the station, and none were accepting cash.
What the hell. Who does that. All I could think was that someone had jammed all those machines specifically to force people to use some specific other mta machine. When I got to a different entrance, and found another machine, I was momentarily scared to use it lest there was a trip wire or identity thieving malware or something.
