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 4 times and everytime they have accepted my 
American Express."
