Found - a billing company once sent my final wire twice, from memory it was about $3000. I could have ignored their request to send it back and there's probably not much they could have done, since I'm outside the USA and it was a 100% final payment (including rolling reserve). I sent it back though.
Lost - nearly lost $250 once when I thought the ATM hadn't issued it. I was pissed off and walked away. Luckily the person behind me was honest and called me back to take the cash sitting in the dispenser...
