The View from Serendip is a collection of essays and anecdotes by Arthur C. Clarke, first published in 1977. The pieces include Clarke's experiences with diving, Sri Lanka, his relationships with other science fiction authors such as Isaac Asimov, and other personal memoirs. There are also reproductions of past lectures, as well as speculations about things of scientific interest. The essay "The World of 2001" had been previously published in Vogue. It predicted the end of menial labor, due to automation and bio-engineered apes.
It's a bit more nuanced than this, but the fundamental dilemma is:
• An overly negative review essentially dooms someone to never working again.
• An overly positive one leads to sticky questions from the next person to hire them (whom you probably know socially).
Clarke's solution is to write ... very closely ... an accurate but difficult to parse recommendation. As I recall, the essay ends with him noting that a household servant he'd dismissed some years before (pursuing a "flim" career) had since returned, to the pleasure of both parties.
Sadly I can't find a copy online -- seems that at a $1.78 purchase price the friction of commerce is excessive here for a 50 year old essay.
Although Clarke did mention Jinadasa, who stole some film rolls from him, Jinadasa left and never came back. However, Appuhamy, another employee, left after four years but later returned. I think you might have gotten the stories mixed up. Anyway, it's an interesting read.
