NathanBurgoine, Me, to Girl Guides at the door selling cookies: "How much are they?"
Girl Guide, crafty and wise: "They're six dollars a box. If you have a twenty dollar bill, I have a twonie for change."
Me, realizing I am in the presence of an entrepreneur, handing over the twenty: "Here you go."
Girl Guide, all sweetness and light as she hands me the coin: "Thank you!"
