Polish Sausage?

A man goes into a store and asks the clerk for some "Polish Sausage".  The clerk looked at him strangely 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 replied, "Well, no"

"And if I asked you for some Irish whiskey, would you ask me if I was Irish?

And what about Canadian Bacon, would you ask me if I was Canadian?"

"Well, I probably wouldn't."

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

And the clerk replied, "Because you're at Home Depot."
