I agree with John about chips leaving the casino door, but I do think that they will keep an eye on those that are trying to leave the poker area. The poker room $1 chips are probably the only ones that have the potential to be taken out of the casino in large volumes because of the low buy value.
They probably figure if you take a bunch of chips from a bj table, etc..that you cashed in $5 or more for each chip and you more than paid for the cost of the chip. It will be tough to take more than a handful of chips from a bj table without them saying "do you want to color them out?"
I will be there that weekend and I hope to collect a few chips. I might even ask if I can buy a set of $1 poker chips. Hey, no harm in asking. The worst they can say is "are you kidding me, get the H-LL out of my casino".
