I've been fascinated on how casinos really attracted gamblers on the games that they have that people come back for more even if they lose money. I'm talking about land base casinos here as it is really very attractive and the atmosphere are different.
It's not only on casinos; its a general practice of every industry, like the food industry and shopping industry; they do it to compel people to play, to buy, and to dine.
Every industry has its own setup to attract clients. its part of marketing. Marketing is everything; people have to see your business as attractive and will cater to what they need. In the case of casinos, they need to explore ways to get people to stay and bet because as long as they are on the casino premises, they will continue to spend.
