Scenario: After a few hours at a $10 blackjack table in Las Vegas, you suddenly hit two blackjacks in a row and find yourself up $150.
How Much To Tip--And Why: $20. Casino dealers aren't tipped as consistently as, say, waiters. But it's good karma (which every gambler needs) to tip an occasional chip or two, especially when you're winning. And absolutely tip the waitresses serving free cocktails: $2 per drink at the minimum. There's no need to tip if you've only played two hands at a table, however. And if you're down a few hundred bucks, tipping the dealer doesn't guarantee your fortunes will change.
