For any Canuck who has never experienced this little pecadillo of current US travel, here's how it goes.
You pull into the gas station and shove your credit card into the reader in the pump. You may get welcomed and offered carwashes or 6-packs of Coke for $1.99. But you will also be asked to enter your postal code. Security thing: the zip is encoded on the card stripe and you might not know the code if you stole the card. OK.
Nice phone-like keypad ... that will in no way accept letters. Numbers only.
