Ways not to lock your bike

Actually did this outside Morrisons in Peckham. Realised just as I began to walk off.
It looked correctly locked up but if you look close enough it's not even around the bloody metal. I don't think anyone would noticed anyway, but still. Would not enjoy a loss and the journey back to Islington.

Felt like a right plum.

I did this (momentarily) at the same Morisons! Was on my Peckham pushie, my mind was addled with flu, chained it up to the flimsy chain that's outside. This thread suddenly came to mind and thought wouldn't it be 'hilarious' if I'd done the same thing. Better just give it a check...
