I respectfully suggest that you're probably white.
Never eaten there, have you? They are almost always packed. A wait is inevitable. You walk in and put your name on a list.
Unless they put "black" or "white" next to your name, you get the table that's free when your name comes up.
As for not getting equal redress when whining about the service? Sounds like a personal problem with the Justice Dept. I say the same thing about them.
This story, is a croc.
