I happened to be walking around with extra cash this week and so I've been buying things, meals at restaurants, supermarket shopping, and the dry cleaners, with real money instead of a credit card.

Without a credit card trail no one could actually track my movements.Would I soon get a knock on the door from the marketing police wanting to know what in blazes is going on?Refraining from using your credit card can be done. If you know how to budget and can take that amount of money out of your paycheck every month and keep it in your pocket, it might be a unique experience. Is it un-American? Is it seditious? I just ate in a fancy restaurant and paid cash. I felt like spy hiding in a strange city.
