The USA Has The Monopoly Over Currency

(I live in Canada. I am with my dad at a local ice cream parlour. We are waiting to order when the woman in front of us starts yelling at the cashier.)

Customer: “NO! I want my change back in American! You hear me?! I don’t want any of your Monopoly money!”

(My dad looks over her shoulder and, sure enough, she is waving a red $50 bill in the cashier’s face.)

Dad: “Madam, I would be more than happy to take that off your hands.”

(The woman snatched up the money and left in a huff. Why is it that some people think they can get the same currency back when they’re in a foreign country?)
