"Can I have some Irish Sausages, please?" asked the Irishman,
walking up to the counter.

The assistant looked at him and asked: "Are you Irish?"
"If I had asked you for Italian sausage, would you ask me if I
was Italian?" demanded the Irishman indignantly. "Or, if I asked
for German Bratwurst, would you ask me if I was German?"

Then, warming to his theme, he went on: "Or if I asked you for a
Kosher hot dog, would you ask me if I was Jewish?" "Or, if I asked you for
a taco, would you ask me if I was Mexican? ! Would Ya? Would Ya?"

The assistant said: "Well, no."
Suitably encouraged by the success of his logic, the Irishman
steps it up a gear.

"And if I asked you for frogs legs, would you ask me if I was
French?"
"What about Danish Bacon, would you ask me if I was Danish?"
"Well no, I probably wouldn't" conceded the assistant.

So, now bursting with righteous indignation, the Irishman says:"Well, all right then, why did you ask me if I'm Irish just because I asked for Irish sausages?"

The assistant replied: "Because you're in f***ing Homebase"
