heres an excerpt from an interview with steve forte to a gaming floor magazine:
he is responding to a question regarding advantage players making a hole in casino profits.
finally, let me respond to the original question, for which the short answer is yes, casinos will overcome the loss. In fact, whether it be poor management or marketing, counterproductive procedures and controls, weak operational philosophies, or an indifference to the importance of game protection, they overcome everything. Some clubs win the money over and over again, and still end up on top. There are not too many things stronger, in terms of making money, than casino games, and it’s easy for poor decisions to go unnoticed and completely absorbed by inevitable profit margins.
