As casinos have a house advantage in games of chance, a casino is more likely over time to take a player's money than a player is to win money from the casino, and thus it is to the casino's advantage to keep a winning player playing. Casinos thus frequently encourage winning players to continue playing. An example can be seen in the Martin Scorsese movie Casino in which Robert De Niro's character ensures that a high-stakes gambler continues to gamble to ensure that the money returns to the casino. On a smaller scale, casinos offer players free alcoholic drinks to encourage them to keep gambling.
