When I was living in Egypt, my favorite tour guide (a Muslim) told me her grandmother had owned a 3-story apartment building in Alexandria. It had Muslims living on 1 floor, Coptic Xians on another, and Jews on another.
Because of the Sabbath rules, she said the Muslim and Xian kids in the building would often run necessary errands for the Jewish neighbors. Sometimes they got paid, sometimes they just did it out of goodness.
And yes, it IS impossible to escape this cliche--when her grandma was sick, her Jewish neighbors brought her soup.
That must have been before 1967, since Nasser drove most of the Jews and "foreigners" out of Egypt after the Six Day War. The foreigners were Alexandria's remaining Greek and Italian communities. Including families who had lived in Egypt for generations, among all three groups. ("Remaining" because he had already purged the "foreigners" and Jews once, after the 1956 Suez Crisis.)
The exiles were given about 2 hours to pack, by most accounts, and escorted to the docks by police where they were put on ships.
This is a pretty good book about 1 Jewish family in Cairo who were exiled in 1963. The author is a reporter at the WSJ nowadays:
