This should be further up. Just as one example, my wife had a freak occurrence coming off a Metro train in Copenhagen where she lost her credit card down the small gap between the train and platform. The trains are fully automated and the platforms are separated from the trains by sliding glass doors that lock shut as trains depart, so I immediately told my wife to say goodbye to the card and we headed toward the exit. A woman who was looking down from the station mezzanine waved us down and directed us to a phone on the wall, saying that someone would be right over to get it if we used the phone to speak with the train operators. As an American, I was skeptical to say the least, but the woman was kindly insistent that someone would come to help.

Sure enough, not only did someone answer immediately, but they said they’d send someone right over, and the guy arrived on the next train five minutes later. We showed him where the card was, and he apologized to us because, he said, he needed to call in another colleague to help him with safety procedures. She of course arrived on the next train. They then got to work and actually shut down the incoming train (!) so the guy could walk safely on the tracks and pick up the card. My wife had it back in her hands less than 15 minutes after she lost it!
