Great call (and a H5)! The underground economy would be bigger than the aboveground one. Like with Food Stamps now.
No kidding! I could see poor people lined up at pumps across the nation with their 'credit' card in hand.
"Excuse me sir, would you like to buy MY gas which is $1.00 cheaper than you will pay if you use your card?" "I'll only charge you $.50/gallon to use my card .... $.65/gallon if you would actually like me to pump it for you. Hell, I'll even clean your windshield for an extra $20!"
Oh yeah, there is some real thought from the DUmbass.
