Maybe you can add to it as what are you think we keep on coming back as if we are under the spell of this big casinos?
I have seen a video on YouTube where the casinos in Japan give bonus SPA and free massages to their player, I forgot the name of the casino, but if this is real, of course, it will add the experience and addiction for players to come every day just to enjoy the massage. Yes we know, we don't need to come to the casino just to enjoy SPA and massage, but the pleasure is a different thing if can relax with the points we got from playing at the casino, right?
