I work as a floorman at a strip casino on graveyard. It is usually incredibly boring on the graveyard shift because everyone goes to sleep around 5 A.M. and doesn't wake up until the afternoon which spans the graveyard hours. I was watching an elderly man and wife playing the Megabucks slot machine for a while one night. After some time the man stands up, talks to his wife and then walks to the bathroom. The wife sits in his chair and starts playing the Megabucks. After a couple minutes I see the husband walk out of the bathroom and towards the machine. While he is walking back I hear a scream. I look over and the wife is screaming because she'd hit the Megabucks. The jackpot was at $11,000,000. The husband runs over to her and stares at the machine, she had only been playing $1 not the $3 needed to take home the 11 million. This 90 year old man turned around and tried to beat his wife with his fists but he was so old and frail he wasn’t doing any damage and not for lack of trying. I had to call security to break up the fight. The security guard that rushed in to break the couple up later said that the wife "didn't want to waste money, so she only played a dollar per spin." They ended up winning $1,000 and nobody was seriously hurt.
