My girlfriend says the top line roughly translates to "Not my type," but her translation of the next line didn't make much sense, so maybe she's wrong on the top line too.
A man walks in to a store and says "Can I have a Polish sausage?". The clerk says "You're Polish sir, aren't you?". The man says "Yes, I am. But that shouldn't make a difference.If I asked for a taco, would you ask if I was Mexican? If I asked for a brautwurst, would you ask if I was German? If I asked for pizza would you ask if I was Italian?". The clerk replied, "No, sir. It's just that this is Home Depot."
