A few lunchtimes back I popped into a mini market round the corner from my flat. As I turned into an aisle I almost collided with two nuns in full habits standing side by side, puzzling over a tin.
One was in her 60s and very slight. The other was a head taller than me and built a little bit like a rubgy player. The taller one waved over the guy at the checkout, who until then had been perched on a stool looking glazed.
The three of them eventually tracked down the product the nuns had been looking for. When the nuns approached the check out, a woman with a laden shopping trolley (who had been queueing quietly) stood aside to let them pass. They nodded at her and went straight up to pay. It was all quite Almodovaresque.
