In Las Poker Room Vegas (I am speaking in the general, no specific casino in mind)- there are etiquette to follow, and to break them means risking any of a multitude of repercussions- from a mild reprimand to outright ban from the premises. First, let me talk about card counting, while it is technically not illegal, this is really in that gray area which is leaning more towards "unlawful"- and why so? Security of these Vegas casinos will make it very hard for a suspected card counter to play in peace, from mild reprimands to a "suggested" leaving. Suggested is not exactly that, if you get my meaning. In Las Poker Room Vegas, the care of your valuables is another thing. If you catch a thief running over your handbag (in the act) and you yell for the security, they would come in full force to your rescue. However, In Las Poker Room Vegas, if you think it is their job to watch over your cellphone or money while you take a half-hour break outside the building, you are wrong.
