Goof: At this point in the episode, the team realizes that they aren't chasing eyedrops anymore, but lead. They are watching a surveillance tape from the casino. Grissom says, "Okay it's the last hand. I'm Doyle. I've been sitting in this chair for the last 13 hours (he really loves the game huh?)." At this point the waitress shows up on the tape. Herein lies the goof. Grissom said it was the last hand. If you remember from the beginning of the episode, the waitress comes in, serves the drinks to the loudmouth kid, who tips her, then she goes to Doyle and serves his drink FROM HIS RIGHT. In the video tape of that hand, you see the waitress come in and serve him his drink FROM THE LEFT. Then she glances at the loudmouth kid, and the episode goes on.
