A business man 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 dont, Ive 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, Ive been to China four times and every time they have accepted my American Express.
