that's awesome.......you probably have more experience than I do, then. but mostly because your family owned a restaurant and you're much older. But I have plenty of "food place" experiences to draw from... and I've never seen Anyone refused service unless they were out of physical or verbally harming other customers...or stealing things...
So, no...I've never seen anyone asked to leave that was even similar to what happened with Mrs. Sanders and her family. If you have, I'd love for you to give me an example....I was not "over the top"...but you are certainly welcome to your opinion

You're in Jersey, right? That might explain the things you've "seen", though...
I spent some serious summers in Chatham and Morristown..
