A guy goes into a store and tells the clerk, "I'd like some Polish sausage."

The clerk looks at him and says, "Are you Polish?"

The guy, clearly offended, says, "Well, yes I am. But let me ask you something. If I had asked for Italian sausage would you ask me if I was Italian? Or if I had asked for German bratwurst, would you ask me if I was German? Or if I asked for a kosher hot dog would you ask me if I was Jewish? Or if I had asked for a taco would you ask if I was Mexican? Would ya, huh? Would ya?"

The clerk says, "Well, no."

With deep self-righteous indignation, the guy says, "Well, all right then, why did you ask me if I'm Polish just because I ask for Polish sausage?"

The clerk replies, "Because this is Home Depot".
