I went to the casino with friends around 12 years ago. We agreed to get a few coins (around 20€ or so) at the beginning, play them and leave once we run out of coins.

Everyone lost their coins except me, I left with like 27€. It was the only time I went to the casino.

So now I can never go in a casino again ! I have a perfect record, I’ve always won against the casino and I intend to keep it this way my whole life.
