If looks could...
When I'm in street photography mode, I rarely take just a single photo of a scene.
My cover activity usually involves fumbling with the controls on my camera. So if the people being photographed notice me, they would be surprised if I simply dashed off. Taking more than one picture sometimes produces unexpected benefits - as here.
I was more than happy with today's extra - I liked the visible headline 'Boris in threat to boycott world'. That was the first of six shots but the blip was an unexpected gem because of this stand-off staring-match outside the coffee shop (I only spotted it when I was uploading the images to the PC).
The two minutes between the shots gave time for the chap on the right to light up his cigarette and send smoke billowing towards the other man.
