Amici, I tried to check this out on Snopes but didn't find.
A friend sent me a warning that when using the credit machine at gas pump, one needs to press CLEAR before and after pumping gas. The contention is that if your credit card number is not "cleared", the attendant (or whoever) can use your credit card number stored in the machine to pump their own gas.
This is a new one on me,; thought it worth looking into.
Anyone have info/opinion on validity?
TIA
