I did not approach any tables. I casually walked by and looked at them without people noticing. Very easy to see.
In the other story, the 7 Stars card was not holding any minimum wage employees hostage. It's something you're expected to show at Caesars if you want them to make policy exceptions for you. The lack of Diamond/7 Stars card is why PIPES had such a miserable time at Paris, as it meant to them that you were a second class citizen. That's how Vegas works.
