...You spend more on your CC's than your wife does...
...You run out to feed the meter with your Freedom card every 15 minutes...
You rummage in your wife's pocketbook every month to change her 'default' credit card.
...You run a cost-benefit analysis on whether to buy your camera on SPG for return/warranty protection or on GCs bought with Ink for 5ppd...
You offer to pay someone's bill in line in cvs anywhere and he pays u in cash!
