As for 'Peeling Oranges?' that's a chastisement we use when someone gets themself a coffee or drink without offering to do the same for others. I can't find any source for it although we suspect it was used by family after the war when oranges came back into Britain and Grandma would peel oranges for the children. While googling the phrase though I did discover this story that touched me.
Ernest Hemingway, the author would spend hours peeling oranges and gazing into a fire before beginning the write a new novel. When he was asked about this, he said he was preparing his soul to write - like a fisherman preparing his tackle before going out to sea. "If I don't do this and think only the fish matter, I'll never achieve anything."
