‘Listen, you little idiot,’ said the mastermind, his patience at its end. ‘These phone calls are recorded, so we speak in code. A “car” is the code word for a fucking kilo of heroin. Didn’t anybody tell you that?’

‘Ah, yes,’ said the Little Idiot. ‘I remember now. Sorry.’
The whole article is worth a read: I like the CCTV story and the Kinder Egg detail too.
