In a casino, every aspect is scrutinized, including the security. Casinos have elaborate surveillance systems, which allow security staff to monitor the casino at all times. Ceiling cameras track every table and doorway, and can be adjusted to focus on suspect patrons. Security cameras record video feeds, which are then reviewed after the event. While casinos don’t use clocks in their interiors, they do use gaudy floor coverings and walls to stimulate the gaming atmosphere. Red is an especially popular color for decorating, which has been found to make people lose track of time.

Gambling encourages compulsive gambling and can be damaging for an individual. Studies have shown that five percent of casino patrons are addicted, which accounts for disproportionate profits for casinos. Many economists find that casinos have a negative economic impact on the communities they serve, because they mainly attract local players, who shift spending from other sources of local entertainment. The costs of treating gambling addicts and lost productivity caused by addiction often offset the economic benefits of casinos.

As a result, casinos make a lot of money off of high-stakes gamblers. In fact, their advantage is as low as two percent. Because there are millions of gamblers, this advantage allows casinos to pay out extravagant comps worth millions of dollars. Furthermore, casinos also provide free cigarettes and alcohol to big-bettors. In addition, high rollers are often surrounded by other people, which adds to their overall gambling experience.
