I was working on the roof of a 16-story building in central London on the ring beam on a cantilever and health and safety came up to me and told me to put my hard hat on, I asked what could fall on my head up here, only god and angles above me, they said its the rules and I have to do it, so I did and the f**king hat fell off and just missed their van parked below, better luck next time I thought,
