I got a working visa for Japan when I was 18 (in 1999), and one night while moving from one hostel to another on the weekend, I fell asleep and missed my train stop. I woke up in the middle of nowhere. It was the last train, it was raining, I had no money on me and the banks were already closed. As I stood there under an awning two ladies asked what I was doing. I brokenly with the help of my dictionary explained the situation. They didn't understand me but flagged down a business man who spoke a little English and he called a taxi, sent it to my hostel and paid for it. It was quite expensive.
