The 2003 movie THE COOLER tells the story of an indebted Las vegas dealer whose only skill was the ability to cool a gambler's winning streak. Anytime I've been lucky at the tables, the house has pulled the losing dealer for a replacement dealer. The house always wins, but gamblers are a suspicious lot and here are some well-known superstitions.
Never sit at seat #10 at a poker table.
Always wear red underwear when gambling.
Singing can be either good luck or bad luck while you gamble.
Don’t count your money during a poker session.
Stay away from sex the night before you play. (Not the most popular superstition).
Never let dogs near a gambling table. (Apparently they’re bad luck and no good at poker).
Never accept being paid with a $50 bill. They’re called “Frogs” and are said to be unlucky.
Never touch someone’s shoulder while he is gambling.
Don’t enter a casino through its main entrance; it’s cursed by bad luck.
Switch on all the lights at home before leaving to gamble.
And never drink.
That's a fact not a superstition and I learned it the hard way in Reno May 1974.
