Menial jobs - most embarrassing?

What would be worse – work as a cheeseburger-ad-placard-holder or being a right royal ‘groom of the stool’?
Dave Cauldwell observed placard holders and worked in some menial jobs himself. He discovered the connection between unhappiness in his personal life and the tendency to blame work issues, the latter providing a cover for the former. He says he's ‘eternally grateful’ for his ‘crappy’ jobs such as cleaning up children’s pee which taught him 'where the boundaries of his own worthiness lay', and that he shouldn’t take himself too seriously! http://www.theage.com.au/opinion/society-and-culture/dignity-found-in-mopping-up-the-mess-20110312-1bs49.html
Again on the question of dignity, Iain Hollingshead reports that Buckingham Palace recently advertised the positions of eco-gardener ($24,000 p.a.), general assistant (wash up) and head of royal travel. Would you apply? http://www.smh.com.au/world/a-licence-to-chill-in-her-majestys-household-service-20110312-1bs7z.html I think Dave might have just read Iain's article, don't you!! Less than fascinating jobs might teach us something about life. What is the worst fear? Losing status? What is the most humiliating job you've done?
