Recently (read last 8 days), I played 2 sessions on consecutive days and unfortunately around the same shift....once right during shift change. Many have debated playing at shift changes, but I found it a winner. There were chip fills to distract, card changes for the pit to do. The only person I saw that was "really sweaty" was the attractive Asian female pit boss.
I played GC and my buy in of several hundred generated attention immediately when I refused to be rated. Within a few minutes, I was approached by a host for my ID etc. I declined again. This ultimnately limited my play because I did not stay too long. The pen was about 75%. I had a nice win.
On my second session, I was watched far less closely than the forst (win was not quite as big and the shift change had then occupied. I was clearly the biggest player in the joint, but still played for 45 minutes.
I am comfortable that I was scrutinized, but ultimately sailed through. While I think they are kinda sweaty, I also believe that they are trying to get customers in and know that they are offering a good game. I also think they are not too quick to identify counters, but they are not incompetent. A couple of other GC players did wander in to the table and provided a distraction . All in all, I spread 1x1 to 2x9 at a high point and sailed in and out no problem. I may have been at my last leg, but the pit boss said, "please come on back!"
