I Am Not Shazam: The protagonist's name is "Holly", not "Tiffany". "Tiffany's" is a jewelry store and the breakfast in question consists of consuming a pastry and coffee while browsing the shop window display.
Also, Lula Mae's middle-aged widower of a husband marrying her when she was barely fourteen. While it's implied that it was a chaste marriage (she remarks that it was annulled ages ago), it would still be impossible to depict such a character as sympathetic today.

I'd settle for [Greta] Garbo anyday. Why not? A person ought to be able to marry men or women or— listen, if you came to me and said you wanted to hitch up with a Man o' War, I'd respect your feeling. No, I'm serious. Love should be allowed. I'm all for it. Now that I know what it is.
