For one day only you can get chocolate coins from a cash machine outside Tate Modern.
Zopa's cash machine can be found on Bankside from 9am on 11 December, awaiting punters looking to get their hands on the sweet stuff.
However, chocolate coins aren't guaranteed, you're only getting them if you've been nice this year. If you've been naughty... well then you get a lump of coal. Chocolate coal. Doesn't seem like much of a punishment to us.
How does the cash machine decide which list you're worthy of? The traditional — and not at all Big Brother-y — method of analysing the language used in your tweets for the last year. You can check ahead to see what list you'd end up on here.
We put Londonist's account through Zopa's algorithm, and apparently we've been 53.53% nice. Yippee. Chocolate coins for us!
