Your are so right!

Those mafia guys were not the brightest ...... they were know for being good soldiers, meaning stupids!!
And Jake was no Meyer, he was actually good with numbers and "showing that he saved money for the group" and he did that in stupid ways.

But, when I meant somebody trying to screw Meyer Lansky, I was thinking somebody outside the casino, players, or lower memebers, If they were trying to make an extra buck, that would have been the least likely casino they would choose. If they wanted to kkep their skin on and without holes.

But, yes, keeping a set of $1 & a table $100 with same black color was completely idiotic.. but that is what they did.
