A man 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 man, 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".
