Halfway home on a long drive, I stopped to buy a comestible from a vending machine. I put in two crisp dollar bills, pushed the button for chips… nothing. I pushed pretzels… nothing. Peanuts… nothing! I hit “refund,” heard two, tinny clinks and knew I’d been hoodwinked. Two bucks invested, two coins in change and no snack. I set about cursing the machine. Drat! Phooey! I scooped the coins into my pocket and drove on. I pulled into the the next rest area and fished the coins out of my pocket. It was a miracle! They were now dollar coins.
