A quiet pint on a Saturday afternoon, last rays of Autumn sun. Sounds nice. But we're sat on a picnic table chained to a wall on a 5 way junction where buses, wagons and irritating charvas whiz past on their mechanical wasps with manky grey jogging pants flapping furiously. The junction's busy, really busy.Then, I feel something fly past my ear and crack then splat against the ceramic tiles of the pub.
