Chips

For my friend's 13th about 15 of us went for a meal at a nearby 'posh' restaurant. They hired a casino, but this one was for kids, so we weren't gambling real money but we played Roulette and Blackjack. You got a cheque in each game counting how much chips you earned, and the person with the most 'money' got a big basket of sweets. I had a good night.
