A while back there was a discussion on why the real soup guy would be upset with the exposure from Seinfeld. Here is an article that may shed some light on the story.
While we're on the subject of Seinfeld, Al Yeganeh, the man who inspired the character of the Soup Nazi, continues to vent over the unflattering appellation he refers to as the "N-word." In a rare interview, the owner of New York's Soup Kitchen International told a Newsday reporter that the show has left scars on his business. "Before Seinfeld, I concentrate. I do my work," said Yeganeh, whose take-out shop was just given a higher rating than the tony Le Cirque 2000 in the latest edition of Zagat's restaurant guide. Since the classic episode, customers are ruder than ever to the soup-obsessed chef. "They curse, they call the name the Soup Nazi.... How the hell could they use that word?" Lest anybody think the Seinfeld parody is a total fabrication, consider that Yeganeh, who admits to being "hyper" and refers to his customers as "trained," has bread delivered to his store every hour to ensure the perfect soup experience. As for his requirements that customers have their money ready, place their order and move to the left, he just wants to keep that line of soup addicts moving. -- SK
