In the movie, Uncut Gems, Adam Sandler walks into a restaurant and bets 24G(24,000) dollars with a well dressed guy sitting and eating at a table.
Adam Sandler tells this guy what stats he bets on in an upcoming NBA game and this well dressed guy writes them down on a piece of paper.
Later in the movie, Adam Sandler makes lots of money from betting in a proper Casino, which is legal.
I am wondering if the first bet in a restaurant is legal? Given it looks so un-official and casual.
