I've been to Vegas twice and played Blackjack poorly but luckily won a small amount. I've been practicing basic strategy so next year I'll know what I'm doing. But I'm not up on what's O.K. to do in casino's, so if I win some chips is it permissible for me to hand some chips to my wife so she can cash them out while I'm at the table and continue playing? She doesn't play Blackjack but likes Roulette and Slots.
