HOLY SHIT.
I used to eat at the Yellow Deli in Chattanooga. Their food is amazing but the vibe is incredible cult-like. Tipping is not allowed. All the workers lived together, wore Amish like clothing.
Then i met a friend who said his sister in law joined the cult a few years back, she began starving her 2 boys as a form of punishment/discipline and when her husband had had enough and attempted an intervention the woman left him to move in with the cult and has never been seen or heard from since.
This is some real shit man and they're still serving Lamb Hambugers down there to this day.
Here's a separate article but I'll see if I can get any more info from my friend.
