Why do blackjack dealers have to paint their nails clear when working?

Probibly so they dont mark, or accidentally mark the cards while handling them.





Savvy players like myself look for and leap to great oportunities such as this, a marked card in a deck can spell disaster for a blackjack table, if a player knows how to exploit it.





Blackjack is already beatable, but when you add marked cards its like taking candy from a baby, when it comes to winning money from the game.
