Attitudes used to be more down-to-earth. Take the case of a Network South East employee's cost-cutting measure at the height of '80s fashion excess.
John Suman worked as a senior railwayman in Dartford, Kent. Like all railwaymen, he was issued each year with two pairs of uniform trousers and a belt.
He noticed that the trousers wore out more quickly than the belt and suggested replacing the belt every two years instead of annually. His idea saved Network South East £10,500 a year and earned him an award of £1,050. How times have changed - though the trains still run late.
