True Story - on 7/7/2007 (a Saturday) after I got out of work, I quickly ran to the bank to cash my paycheck before they closed at 1pm. After cashing my check I jumped on the interstate to St. Louis for a weekend at Harrah's. When I got to the hotel and checked everything, I noticed an extra $100 in the envelope the bank had given me with my cash receipt - although the receipt showed the correct amount I was supposed to get.
So I did what I always do - bought a $35 seat in a in a pool of 90 (10 table) Texas Hold 'em Tournament. About 6 hours later I was $465 richer for taking 2nd place. I lost with a spade flush - he had a full house - 8's full of jacks.
When I returned home Sunday I had a message from me mum about the cash from the bank (she's neighbors with a bank employee). When I called her back, she only had one piece of advice for me: keep it (not knowing what I did the night before).
But why? I asked my very honest mother - because it was the teller's error - and the neighbor admitted that the bank didn't catch who the error was given to - and if it was given to me, to keep it.
The bank had narrowed it down to three people, myself being one of them. But the fact of the matter was simple, they didn't know. They called the other potential people that may have received the cash, but none confessed to having the extra dough - and neither did I.
Monday morning I received a few nasty phone calls from the manager of the bank, stating that I needed to come and pay them $100 or they were going to take it out of my account. I stuck to saying that I didn't receive the cash. I also let them know that I knew I wasn't the only one at suspect.
Come to find, they had bullied the other two parties to "come down" and "pay them" $100 - but they didn't. No money was ever removed from my account, either.
