I have been to Las Vegas before and watched sports in the Sportsbook lounge. However, I see these small cubicles with individual TV's in them. Most of the time I see bettors watching horse racing on them. So as not to offend anyone while there what are the gamblers etiquette rules? Are the TV's only for horse bettors? Do you need an invite to sit at one? Is it first come first serve? Is it only available to larger bettors?
