It's OK for private business owners to have rules, but it's not OK to be unreasonable about their enforcement. So, he has a rule no parties over 4 people, fine. But when a party of 5, 6, 7-8 politely agrees to split in half, kicking them out is unacceptable. Especially when foul language, totally unprovoked, is involved.
As other reviewers have said, this is a nice slice of life in our largest and meanest city. I love food, and good restaurants. I totally support mom and pop's and spurn chains whenever I can. Usually the quality is much higher, because mom and pop's aren't being driven by Wall Street investors looking for the max return on investment at all costs to the consumer. The M&P's are actually run by real humans who, of course, need to make a profit and living, like the rest of us, but *may* still have some pride (and some shame) in what they are doing. Usually a much better bet than the investor backed chains.
I found it a very entertaining little documentary, and I wish the family the best, but it is no accident that the YouTube page I found it on also has many links that debate the difference between psychopath/sociopath, and some serial killer docs as well.
New York's "friendly" neighborhood restaurant proprietor has a marked mental illness. Mostly I feel sorry for him, his family and his masochistic patrons.
Don't believe me? Look up reviews on Yelp.
