Strange how things go round in this funny old world.
When the Brits were building the Suez canal years ago they employed thousands of local Egyptian labour. The work deal included free food in large Mess tents adjacent to the diggings. The local Arabs heard of this largesse and walked out of the desert and joined the workers queue for free nosh. The Brit Boss men cottoned on to this excessive ration bill so determined who were the genuine workers and then had the acronym "Workers On Government Service stencilled on the back of their dish dash. I suppose if they had them they would of used wristbands back then! :-) Things have improved!
//It can be an acronym for several other things:
•"Whole Of Government. Used to describe Australian Government-wide outsourcing contracts"
•"Working On Government Service, referring to Indians working for the British Raj, or referring to Egyptian labourers working on the Suez Canal during the British Occupation in the early 20th Century."//
