A man goes into a store and asks the clerk for some "Polish Sausage."

The clerk looked at him and asked "Are you Polish?"

The guy, clearly offended, says "Well, yes I am.  But let me ask you something.  If I asked you for Italian Sausage, would you ask me if I was Italian?  Or, if I asked for German Bratwurst, would you ask me if I was German?  Or if I asked you for a Kosher Hot Dog, would you ask me if I was Jewish?  Or, if I asked you for a Taco, would you ask me if I was Mexican? Would ya, huh?  Would Ya"

The clerk says, "Well no."

"And if I asked you for some Irish Whiskey, would you ask me if I was Irish?  What about Canadian Bacon, would you ask me if I was Canadian?"

"Well, I probably wouldn't,"

With self-indignaton, the guy says, "Well, all right then, why did you ask me if I'm Polish just because I asked for Polish Sausage?'

The clerk replies, "Because you're at Home Depot."
