Oh absolutely. I have two good friends who are dealers and they absolutely LOVE when people play for them. I think as a dealer you inherently have to love the game, and so playing and the opportunity to double down and split right along with the player adds to the fun and excitement of winning for both parties.
When I win a lot, sometimes I'll even play the entire last hand for the dealer (my bet as well). If I bet $10 on the hand, and $2 for the dealer, that's a nice $24 they will make if I win, because I let them keep the whole hand. I'll simply push the chips forward and tell them "it's all you"! You should see the smiles you get (especially from some of the beautiful Asian lady dealers!!)!
And let me tell you, they will remember you. I have had several occasions where the dealer will light up and smile when they see me sit down.
Ain't winning great?
