If you can imagine, a 60+ woman was playing a slot machine at MGM Detroit, hit a $30,000 jackpot and then walked away from the machine and left the casino. The woman had not collected her prize and was apparently unaware she'd won. The casino used her player's card info to call her and found her phone number was disconnected, they sent her a letter via US post. Despite thinking the letter was hoax, she contacted the casino, a month later, and did indeed collect the prize.
1. Use your player's club card, always
2. Don't gamble if you can't tell you just won a $30,000 jackpot. :O
