what is a card shark? it is someone at the tables, usually playing poker who is going to eat up the table alive. You can't really find any dealers and call them a card shark although many blackjack players like to do this thinking the dealer is responsible for their losing streaks. This is just poor sportsman ship and the same can be said at the poker table where the dealer has no influence on the outcome.
Of course players will tip the dealers and the dealers will gladly take credit for when the cards are hitting in their favor. This is one of the benefits of being a dealer but sometimes it isn't worth it when you get rotten people at the tables who swear, give you dirty looks and blame you for losing. It makes you wonder what is going through their heads as a blackjack dealer or a poker dealer thinking this person is a complete moron and losing all their money. Remind me not to become as rotten as this guy.
So in short if you don't like card sharks then don't swim with them. Enjoy playing the game of blackjack or poker recreationally but leave it at that. If you want to take it professional you're in for a rocky ride.
