Carl's Jr. review: denial of valid credit card

Carl's has instituted a software screen that denies a second use of the same credit card to deter theft by employees who run duplicate charges and remove cash from the register. The problem is customers like me are denied service if a second item of the same price is desired during a visit. When this was reported to Carl's Jr. Customer Relations I was told nothing prevented me from finding an ATM to get cash and return to make a second purchase. That is beyond stupid. Carl's just lost another customer.
