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!
