Check my reasoning on this
Suppose I were willing to toke $1 on each of 100 hands. On average I will win 43 hands, the house will win 48, and 9 will push.
If I always give the toke, the dealer gets $100, regardless of win,lose or push.
If I bet the $1 for the dealer, the dealer gets $2 on our wins,for a total gain of 43x2=$86. The house loses $43 paying the dealer's part of the win.
On our losing hands, the dealer gets nothing, and the house gets 1x48=$48.
If this reasoning is correct then:
1) The dealer should prefer to be given the toke since he gains $14.
2) The house should prefer that I bet the toke since it gains $5.
3) I would rather give the toke so that it all goes to the dealer and nothing to the house. (It would cost me $9 more to give because if I bet the toke the pushes would have no cost.)
(BTW - In the local casino, where I am well known, I don't do either of the above, but at the end of a winning session I will hand the dealer a small percentage.)
