Funny Joke: American versus African

An American man walked into a restaurant in
London.As soon as he entered, he noticed an
African man sitting in the corner.
So he walked over to the counter, removed
his wallet and shouted, “Waiter! I am buying
food for everyone in this restaurant, except
that black African guy over there!”
So the waiter collected the money from the
man and began serving free food to everyone
in the restaurant, except the African.
However, instead of becoming upset, the
African simply looked up at the American and
shouted,
“Thank you!” That infuriated the man. So
once again, the American took out his wallet
and shouted, “Waiter! This time I am buying
bottles of wine and additional food for
everyone in this bar, except for that African
sitting in the corner over there!”
So the waiter collected the money from the
man and began serving free food and wine to
everyone in the bar except the African.
When the waiter finished serving the food
and drinks, once again, instead of becoming
angry, the African simply smiled at the
American man and shouted, “Thank you!”
That made the American man furious. So he
leaned over on the counter and said to the
waiter, “What is wrong with that African
man? I have bought food and drinks for
everyone in this bar except for him, but
instead of becoming angry, he just sits there
and smiles at me and shouts ‘Thank you.’ Is
he mad???”
The waiter smiled at the American and said,
“No, he is not mad. He is the OWNER of this
restaurant.”
