A man walks into a store and asks the clerk, "Do you have any polish sausage?"

The clerk replies, "Are you Polish?"

The man says, "Yes, but why do you ask? If I asked for Italian Sausage would you ask if I was Italian? Or if I asked for German Sausage would you ask if I was German? Or if I asked for a taco, would you ask if I was Mexican?!?

The clerk simply answered, "No."

The man said, "Then why did you just ask me if I was Polish?"

The clerk replied, "Because this is a hardware store!"
