An Indian walks into a cafe with a shotgun in one hand pulling a male buffalo with the other and says to the waiter, "Want coffee."
The waiter says, "Sure chief, coming right up!"
He gets the Indian a tall mug of coffee. After drinking the coffee down in one gulp, the Indian turns and blasts the buffalo with the shotgun, then just walks out.
The next morning the Indian returns. He has his shotgun in one hand pulling another male buffalo with the other. He walks up to the counter and says to the waiter,"Want coffee."
The waiter says, "Whoa, Tonto! We're still cleaning up your mess from yesterday. What the heck was that all about, anyway?"
The Indian smiles and proudly says, "Training for upper management position. Come in, drink coffee, shoot the bull, leave mess for others to clean up, disappear for rest of day."
