1- We're such a small drop in the bucket compared to what casinos spend on their chips.
2- I think the Borgata incident has a lot to do with the Paulson home market drying up. That was a huge security breach, that caused a lot of embarrassment. You noticed since that happened, that Jim has had nearly as many chips to flip from The Chip Room? I'm sure after the Borgata (that wasn't the only incident BTW), many casinos saw Paulsons on the secondary market as a potential security breach. IMHO, the put pressure on GPI to close that loophole. GPI obliged because ( see point 1)
PGI's unique molds for the home game market took care of any security issue.
