I'm willing to bet that the restaurant doesn't even exist...someone from Stormfront probably wrote the article to describe a possible loophole to allow segregation.
I'd say that's about right. It's inconceivable that the family of a young man would laugh after he called the waitress a bitch, just for bringing the wrong beverage. And that part about taking fried chicken off the menu gives the writer away.
No it's not when you're dealing with black people.
