Reminds me of a probably-apocryphal story I read somewhere years ago. "I was in a casino, and saw a doddering old man sitting not at a slot machine but at the change machine. He fed in dollar after dollar, and would cheer and call out 'I won again!' every time it dispensed his quarters. It was harmless, and better he 'play' that than lose at a real slot machine, so I left him alone with his fantasy. I saw him again the next day. I pointed at the change machine and asked why he wasn't playing that one since it was his favorite yesterday. His reply: 'It was dispensing six quarters for every dollar until they fixed it.' "
