Casino dealers are not particularly well paid by Casino's and if tipping is allowed in your Casino the dealers wage may be depending on your generosity as a player. Always remember to give the Blackjack dealer a tip if your are winning on their table (and if it is acceptable in that particlular Casino, of course). But if you are winning and wish to tip the dealer, a small tip every hour or so during play is sufficient. It is important not to over-tip as your luck could change at any moment and the dealer could end up taking home more of your winnings than you. A popular way to tip the dealer is to place a bet for them. Position your bet for the dealer near your own chips in the betting sphere so if you win, the dealers chip will also win and they will have earnt double the tip. Another way is to notify the dealer that their tip is riding on your coat tails. This is accomplished by placing the dealers tip bet on top of your own chips, and if it wins they take the winnings from the tip bet as a tip. But rather than also taking the original tip bet stake this carries over to the next hand, again if you win they take the winnings from the tip bet and so on until you lose a hand. This way as long as you are winning the dealer will get a tip each hand while they are riding your coat tails.
