from an RAF attached Metperson's viewpoint:
Best Guetersloh, with Nicosia 1961-64 close behind.
Worst [which I avoided by the skin of my teeth] was Ocean Weather Ships, converted corvettes, scarcely seaworthy, manned by reprobates and piss-artists, very little work to do, food dreadful etc.
One only had to meet the weather ship people to realise what pondlife they were. I was posted so played every card I had. Fortunately I was PA and gopher to a very senior officer who discovered that he could not afford to lose me to the ocean deep.
Phewww!
