Why do casinos lavish such gaudy gifts on someone who has just taken piles of their money? To ensure he doesn’t leave. The more gifts they give, the longer the gambler will stay. The longer he stays, the more likely he is to cough up his winnings. In fact, because of the false sense of his own skill he acquired while racking up his temporary purse, he’ll probably end up losing far more than he would have tolerated had he not found himself up in the first place. However cautious and determined people are when they begin, their good judgment goes out the window once they start to win.
