A casino is a place where people can gamble and play games of chance. While the typical casino adds a lot of luxuries to make it more attractive, there have been less elaborate places that housed gambling activities and would still qualify as casinos.
Unlike other businesses that are based on service, casinos are almost entirely based on the sale of money. This is why casinos have such strict security measures. Casinos have to be very careful because cheating and theft are common and there is an ever-present concern that someone will take advantage of the high amounts of money being wagered.
One of the reasons why casinos use chips instead of cash is to make it harder for patrons to steal or cheat. In addition, chips are more easily tracked by security. Casinos also have a number of other security measures in place to make sure their patrons are safe. For example, dealers are monitored by pit bosses and table managers and each table has a “higher-up” person watching it. This way, a cheat can be caught before they can get away with it.
Casinos try to keep their patrons in the casino as long as possible to make as much money as they can. This is why you will not find any clocks on the casino floor and some even prohibit dealers from wearing watches. Casinos also make the games with the lousiest odds (such as craps) more attractive by amping them up with flashing lights and bright colors. This psychological manipulation is intended to encourage people to gamble more, even if they know the odds are stacked against them.
