I was scammed at the airport in Mobay in April at the airport. My CC company caught it. This last week I purchased duty free at the Mobay airport with a CC with a pin#. The clerk and her manager insisted that I sign. Even though the receipt clearly stated that no signature was required. They would not release my purchase. So I drew a line on the paper as my signature and they accepted it. I have also been scanned in an airport in Poland. Airports worldwide are hotbeds of fraud.
