Mel, This has nothing to do with "fat profits". It has to do with the integrity of the game. "Cheating" A casino does not know a collector from a cheater. Maybe a collector, when caught, could have security call his Mommy. She could vouch for him as no cheater. He could then have the roulettes.

I am quite sure that a cheaters Mommy would never vouch for him.

Roulette Fact:

Take a roulette chip at a 50 cent buy in.
Play it back at a $1 buy in.
You have won 70 to 1 instead of 35 to 1.

I think that math is right, I never play the game.
