Another Bunnings joke

A customer asked, "In what aisle could I find the Guinness?"

The shop assistant asks, "Are you Irish?"

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 Polish sausage, would you ask if I was Polish?"

The shop assistant says, "No, I probably wouldn't."

The guy says, "Well then, because I asked for Guinness, why did you ask me if I'm Irish?"

The clerk replied, "Because you're in Bunnings'."
