The longer you are in the casino, the higher chances that you lose your money. They make you feel comfortable inside the casino so that you won't think of leaving, that's their strategy.
What you said its true. But we lose in the end isn't because we feel comfortable with the games, it's because we got beaten by house edge.
That's the bottomline in every casino, to earn as much money as they can from the players. They will do everything to make you stay and not worry about the time until you end up broke and no more in your pocket. But a gambler should know all about that. They are not there to rip off the casino but it is quite the opposite.
