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,
if I had asked for Italian sausage would you ask me if I was Italian?
Or -- if I had asked for German sausage, would you ask me if I was
German? Or -- if I had asked for a taco would you ask if I was Mexican?
Huh? Would ya?"
"The clerk says, "Well, maybe not."
"With deep self righteous indignation, the guy says, "Well, all right then,
why the HELL did you ask me if I'm Polish just because I ask for Polish
sausage?"
The clerk says, "Because this is a hardware store."
