I have a PayPal debit card (mastercard) that I get 1.5% cash back on for whatever I spend. I always use the card to buy gas because of that.For some reason, the last few weeks my card won't work at the pump. Not sure exactly what the reason is...remember, it's illegal for me to pump my own gas here. I have to go inside where they swipe my card and make me sign the receipt.Anyone have any idea why this might be happening? The card still works fine anywhere else. And it's happened at 3 different stations. Normally when I pay at the pump they take out $1 immediately, and then the full amount a few days later. When I go inside they take out the full amount right away. What's the difference??I would just ask PayPal, but the only response anyone ever gets from their foreign support is a prewritten answer to a question you didn't ask.
