I was watching Goldenballs (gameshow hosted by Jasper Carrot) yesterday and basically they got to a jackpot of over £40,000. They were both very excited about getting the money when it came to the question of whether they were going to split it or try to steal it from each other. Now they had both agreed that they would split it and take just over £20,000 each but the guy was bluffing and chose to steal the money instead. I can't believe how smug he looked at ripping this poor girl off for £20,000. I think it would be alright if it was a small amount of money but that kind of money could change someone's life and I don't expect she's going to get over it that quickly.
So what would you do? Personally I don't think I would be able to contain my anger and I would jump on the other person and start ripping them to pieces. Either that or I would control myself and set upon somehow costing that person at least that amount of money in the future. Maybe destroy a car or two.
