Cheat… Change machines
Got a small mountain-range worth of laundry and only a couple bucks to wash it? Take one bill (a George Washington, for example) and lay it on a table faceup. Next, take another bill of the same denomination and lay it facedown. Match the short sides of each bill to absolute perfection and tape them together—it must be seamless. Feed one end of your two-headed money into the change machine. It will recognize the first bill but reject the second bill because it’s backward. You’ll get a dollar in change, and you’ll get your money kicked back at you all in one stroke.
