Seinfeld: The Soup Nazi Episode ??

It is a real place - I've been there a couple times, although not while the actual Soup Man was around, so I can't attest to the man's character. But he sounds like a genuine ass and his portrayal probably not too exaggerated. en.m.wikipedia.org/wiki/The_Original_Soupman

Soup was pretty good, but not so good I'd put up with being yelled at by the proprietor. It's pretty hard to fuck up soup.
