i used to be a bus-conductor in Liverpool in the 60s. We used to wait with engine running for the ferry to arrive and the commuters to come up the gangplank, not running (that would be undignified) but definitely hurrying. Then I would give the bell and we would be away with a dozen or so city gents left fuming with silent rage and waving their brollies. Our daily fun, if we judged it right. Added spice to an otherwise boring shift. One up for the working classes!
