A businessman called

A businessman called and had a question about the documents he needed in order to fly to China. After a lengthy discussion about passports, I reminded him he needed a visa. "Oh no I don't, I've been to China many times and never had to have one of those." I double checked and sure enough, his stay required a visa. When I told him this he said, "Look, I've been to China four times and every time they have accepted my American Express."
