Well, kind of... I was at the counter and the register drawer was open. I saw it and asked if I could have it. They obliged, and put another nice fingerprint on it as they pulled it from the till and handed it to me!
That's pretty neat. It's still in wonderful condition. I had almost the same thing happen to me at subway, but I found a 2011 proof territories Washington quarter in their tip jar. I asked the woman if I could have it and that I'd bring in a few more quarters in to trade for it haha, but she didn't understand what I was saying so I just grabbed it and brought her back a dollar, she was very thankful for that, but didn't understand how excited I was to find a proof quarter in her tip bucket.
