@MontereyJack,
Angel cake cream mixer.
Have we had that before Jack? What you might try is going through a dictionary entry of the letter and from it think up something a bit daft, an actual occupation of a member of the proletariat rather than some big cheese and with a touch of ambiguity to it.
There are angel cakes in the shops. They are 3 layers of differently coloured cake separated by a layer of cream. Now some poor sod, probably a lady if it's a small scale angel cake factory and wearing a hat approved by the food standards agency to ensure no loose hairs or nits fall into the cream, has to mix the stuff to get it to the right consistency for spreading. It's an occupation. It's her full time job. If it's a large scale operation such as Mr Kipling's "Exceedingly Good" cakes it will be a team of blokes with vats and spreading and slicing and wrapping machines.
I hope you don't think ordinary occupations of exceptional utility are beneath your dignity because if you do you're on the wrong thread. I daresay there are a lot more zoological garden cafeteria table swabbers in this world, bless their gently beating little hearts, than ******* Zen masters. And a bloody good thing it is too.
