As a just retired craps (and blackjack) dealer, I gotta tell you that the stickperson (nor any of the other casino workers) should really care. If the stickperson is passing the dice with a seven showing to a right-way bettor or with the point number showing to a wrong-way bettor, (s)he probably isn't expecting a tip from that player.

Playing craps is about socializing. People in general don't like to be the first person to come to a dead craps game.

I've dealt to a whole table full (about ten people) of don't-pass bettors and they were having a ball yelling for the seven-out. A right-way bettor came to the table and they booed him away. The crew catered to them. We rooted for the seven because the players wanted the seven. And they tipped us.
