Old Jewish Beggar

An old Jewish beggar was out on the street in New York City with his tin cup.
“Please, sir,” he pleaded to a passerby, “could you spare seventy-three cents for a cup of coffee and some pie?”
The man asked, “Where do you get coffee and pie for seventy-three cents in New York? It costs at least a dollar!”
The beggar replied, “So who buys retail?”
