The thread has apparently been deleted, no real surprise there given the context of the story.
I think it was the Jack Casino Cincinnati, where the PCF member had played and previously harvested many racks of chips (along with racks) on multiple occasions. The PCF member returned (presumably to just play, not harvest), was approached by security, and taken to a back room for questioning. They were expecting him. After hearing his story about why the chips were removed (for resale on PCF to chippers), the bottom line is that they really didn't seem to care about the chips any longer, but demanded that the racks be returned. He wasn't banned, but they made it quite clear that nothing belonging to the casino should be leaving the casino by his hand in the future. My guess is they were likely more concerned about him using the chips to make counterfeits and returning with fake copies or counterfeited larger denominations made from the chips he took. But they were certainly aware of what he was doing, directly confronted him on it, and could have pressed charges, but chose not to.
Personally, I'd prefer to not ever see the back rooms of a casino under those circumstances. Sounds mighty -EV to me.
