Chinese and American are in a plane.
Suddenly, the Chinese man puts his shoes off and the American is angry.
After some time, he goes to buy a coke, but the Chinese say that he’ll do it.
While he’s gone, the American spits into his shoes.
The Chinese get back and the American drinks his coke.
That repeats a couple of times,and after the flight the American admits, “I spitted in your shoes, sorry. “
Chinese answers, “That’s how we do it. We spit in each other’s shoes, we piss into each other’s cokes… “
