An American man walked into restaurant in London. As soon as entered, he noticed an African man (black) sitting in one corner. He walked over to the counter, removed his wallet and shouted "waiter i'm buying food for everyone in this restaurant, except that black man over there. The waiter collected the money and began serving free food to everyone in the restaurant except the black man. Instead of become upset the black man simply looked up at the American and shouted "thank you". This infuriated the american. So once again the american repeated again to buy bottle of wine to everyone except the black man. The black man smiled and shouted " thank you " to the american man. That made the american man furious. So he leaned over the counter and asked the waiter, what is wrong with that black man? I have bought food and wine to everyone in this restaurant except him, and instead of becoming angry, he just sits there smiles at me and shout "thank you
