As a casual observer and as a complete beginner to living 'foreign' it's quite fun to watch what goes on around.
My current obsession is to predict which bank note the customer in the shop will use to pay for their shopping. Coins are rarely handed over unless asked for. The euro still hasn't taken off yet even after three years, there is still confusion when the customer is asked for any change by the shop assistant and usually shows a huge handful of coins with no idea what to use.
