Policeman on duty in St Johns Road in Clapham, on the front line for over 8 hours, drops his riot shield and runs back down the street, into Sheigate Street and then down Leathwaite Road.
An arm comes out and stops him. "Where do you think you are going, Sonny?"
"Sorry, Sarge, I have been on the front for over 8 hours, pelted with stones, bricks, shyte and petrol bombs. I needed a break from it."
"I'm not a Seargant. I am a Chief Inspector."
"Sorry Sir, I didn't realise that I had run that far....."
