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 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."
