Поломать голову

Вот, с reddit'а некая история:
Dear Reddit, I work in NYC, and was dragged into a very curious situation today. I was taking the 1 train from midtown to the financial district and as usual, the train was pretty packed. I bumped into a raggedy dressed man as we got on and he shot me a quick smile. I though nothing of it until he went to get off at 14th street and he handed me a $50 bill along with a note. Before I could even open my mouth to ask him a question, he was gone. Below you find pictures of both the front and back of the note.
Там длиннющий тред. Если есть время и желание, конечно.
