An Arab walks into a bar and is about to order a drink when he sees a guy close by wearing a Jewish cap, a prayer shawl, tzitzis and traditional locks of hair. He doesn't have to be an Einstein to know that this guy is Jewish.
So, he shouts over to the bartender so loudly that everyone can hear,"Drinks for everyone in here, bartender, but not for that Jew over there."
Soon after the drinks have been handed out, the Jew gives him a big smile, waves at him, then says, "Thank you!" in an equally loud voice. This infuriates the Arab. He once again loudly orders drinks for everyone except the Jew.
As before, this does not seem to bother the Jewish guy. He continues to smile, and again yells,"Thank you!"
The Arab asks the bartender, "What's the hell is the matter with that Jew? I've ordered two rounds of drinks for everyone in the bar but him, and all the silly bugger does is smile and thank me. Is he nuts?
"Nope," replies the bartender. "He owns the place."
