Racism?

Everyone seems to be in such a hurry to scream ‘racism’ these days.
 
A  customer asked, “In what aisle could I find the Polish sausage?”  
 
 The clerk asks, “Are you Polish?”
 The guy, clearly offended, says, “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?
Or if I asked for some Irish whiskey, would you ask if I was Irish?”

The clerk says, “No, I probably wouldn’t.”

The guy says, “Well then, because I asked for Polish sausage, why did you  ask me if I’m Polish?”

The clerk replied, “Because you’re in Home Depot.”
