Queen Elizabeth II might be the epitome of British decorum, but when it comes to finances, she's kind of like your own grandma. Here's one of the queen's most surprising money habits: she only carries cash with her on Sundays, because — like your grandma — she "donates to the church collection basket." A source close to the 90-year-old monarch adds, "Her butler irons a 5-pound note into a little square by folding it until you can only see her face." How amazing is that? Just carrying around money with your own face on it and making it rain during Sunday service!
