...Know when to run

$1-$2 Limit Texas Hold'em: +$1.50 (hooray!)
Slots: -$5.00
Blackjack: -$13.50
Roulette: -$(not good) (Always bet on black? Sometimes it comes up red! It would have been more efficient to just hand over $20 to the dealer, and $20 to one of the other people at the table.)

Somehow, I don't think Rule #1 is "Take care of your dealer".

And what does a card shark look like? Could be a young woman from California, who bats an eyelash and smiles sweetly while professing to have learned poker the day before, then laments just missing an up and down straight draw on the next hand...
