He sits down and orders a beer. While drinking his beer he notices an old Jew sitting down at the corner of the bar. The Nazi finishes his beer and then tells the bartender he wants to order a round of beers for everyone at the bar, except for the Jew.
The bartender pours up a round of beers for everyone. The Nazi gets his beer, looks at the old Jew, raises his glass and taunts him with a "Sieg heil!" But the old Jew just smiles.
After a while the Nazi orders another round for everyone, except the Jew. Again, he taunts the Jew with a "Sieg heil!" before downing his beer. Again, the old Jew just smiles.
This goes on for a few rounds, until finally the Nazi asks the bartender what the hell is with the Jew who doesn't get any free beer and just smiles when I say "Sieg heil"?
The bartender replied, "Well, the Jew owns this place."
