In the wild western movies which I think also show history where card tables are inside the salon or a whorehouse, people have to surrender thier weapons before going inside. That's kind of a KYC.
Lol, watching too much movie eh..

Most of the created movies is part of the writers imagination there maybe some truth to it but most them are fiction.Unfortunately, this is especially true with regards to gambling. I love movies and I watch a lot of them, and I can say that in the past 15 years or so, movies have been great in showing and explaining some scientific and historical facts, but never in my entire life I saw a film where gambling experience was depicted realistically. It is always only partly true, and this part is normally very small.
I guess you could even talk of the movie "the big short" as kind of an historical mega-betting, but from Wall Street. For those who have not seen it, it is about a well know hedge-fund manager that, in the moment of the biggest housing bubble known to humankind see further than the rest and decides that it is the moment to take a "short" position (selling without having the asset). I will not spoil the end, but it is a real superbet.
