A casino is an establishment for gambling. The most well-known casinos in the United States are in Las Vegas, Atlantic City, and Chicago. Many casinos feature musical shows, lighted fountains, shopping centers, and other entertainment, in addition to their gambling operations. Casinos earn millions of dollars each year from patrons, who place bets based on the statistical odds of winning. Casinos make money by taking a percentage of the bets, called the “vig” or the “rake”, or by paying out winning bets in accordance with a game’s rules. A casino also generates revenue through the sale of food, drinks, hotel rooms, and merchandise.
Security at a casino is a high priority, and most casinos employ many methods to prevent cheating and theft. Staff members watch patrons and games closely, noting suspicious behavior and betting patterns that could indicate cheating. Elaborate surveillance systems offer a high-tech “eye-in-the-sky” that allows security personnel to monitor every table, window, and doorway in the casino at once.
There is also a more subtle aspect to casino security: The expected actions and reactions of players, dealers, and other personnel follow certain routines that are easily recognizable when someone deviates from them. This may be a minor thing, but it can give security people an edge over crooks who want to steal.
