Few years ago, I’ve detained a bag thief who was a foreign national and wasn’t best pleased. He kept shouting at me: ‘Clock. You clock’ I was puzzled but didn’t respond. Whilst we were waiting for the van, he continued to shout: ‘You’re a clock you!’ Eventually I asked him what he was on about to which he pointed to his groin and said: ‘You. You’re clock’ At this point I couldn’t help but smile and said: ‘I’ll be a clock any day mate’ The probationer I was with couldn’t stop laughing.
