Don't mind the laughing
A Native American 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 Native American a tall mug of coffee. After drinking the coffee down in one gulp, the Native American turns and blasts the buffalo with the shotgun, then just walks out.
The next morning the man returns. He has his shotgun in one hand pulling another 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 was that all about, anyway?"
The Native American 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."
