To be fair, the distortion probably had more to do with him waving my feeble camera phone away, than any psycho abilities Dad’s Army may have picked up. "Please delete that picture right away. That is an army building". Naturally I didn’t, and came back later with a proper camera with zoom, because I am a childish twat.
