How did Francie insult the pickle man in "A Tree Grows in Brooklyn"?NO
On pickle days, Francie goes to the Hebrew man in the neighborhood store to buy a Jewish pickle.
When she goes to the store, the old Jewish man gets insulted when she asks for a "penny sheeny pickle" (Smith) Francie does not know that the word sheeny is an insult to Jewish people.
It is a slang word used to call Jews, kike or hebe, or worse. Francie uses the word without knowing what it means. But the Hebrew man can't stand the little Irish girl.
