Three hungry men

There three men living together. An Afro-American, a West Indian and a Nigerian. They were all starving because they didn't have money to buy food.
They took a walk and on approaching a restaurant in this classy neighbourhood, they came up with a plan.

The Afro-American went in first. After being seated, he ordered a three course meal with white wine. When he had finished the meal, the waiter came by with the bill. LISTEN MAN, I ALREADY PAID YOU! the Afro-American shouted! The waiter was very confused because he could not remember being paid. But because he did not want to cause any trouble, he let him leave.

Five minutes later, the West Indian walked into the same restaurant and ordered a five course meal with red wine. When he was finished eating, the waiter came by to collect the money for the food. HEY, HEY, LOOK AT ME CLOSELY. BUT I PAID YOU ALREADY! the West Indian shouted. This time the manager came and had to calm down the West Indian, because he did not want anything to upset the other customers. He let him go.

Ten minutes later, the Nigerian walked in. He sat down. Lit up a cigarette, and ordered the most expensive meal on the menu, plus two bottles of Wine. After he had finished, the waiter came to collect the money for the meal, but before the Nigerian could say anything, the waiter spoke to him. "Sir, I have been having all sorts of problems all day and I cant understand it. Two other people like you came in earlier and ate, and they say that they paid me but I dont remember getting any money from them so - Before he could finish, the Nigerian interrupted, rather emphatically, OGA I'M SORRY, BUT THAT'S YOUR PROBLEM. I JUST WANT YOU TO GIVE ME MY CHANGE!!!"
