Racism

Everyone seems to be in such a hurry to scream 'racism' these days. 
A customer asked, "In what aisle could I find the Sarson Da Tel?" (Mustard OIL)
 
The clerk says  "you a Sardar?" 
The guy, clearly offended, says, "Yes I am.  But let me ask you something.
If I had asked for Italian Olive Oil, 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 Sarson Da Tel, why did you  say I am a Sardar?"
      
The clerk replied, "Because you're in a Liquor Store."
