I know what you're talking about, and this is one of the ways I always mention when these fools come here talking about betting systems.

The ways to beat roulette:

1. Rigged game (ie dealer shooting for your section)
2. Flawed wheel (don't even bother)
3. Prediction using physics, almost only done with a computer. These do actually exist but they are illegal. I believe it's 1 year in jail and/or a $10k fine.

Now croupiers aiming for the empty sections of the wheel, is that because you guys are evil or because the management encourages it? If you find an experienced dealer and bet on the emptier areas of the table will they still try to screw the table or move to just wanting to screw you?

Peronally I wouldn't think the dealers & croupiers would want you to lose. You'd want to work in a positive/friendly enviroment. I guess that's why I'd assume it's the management encouraging it.
