All those people in that picture are ignorant about online gambling? Why they are waiting on queue to gamble such a stupid thing and more we are not going to have any fun with such crowded place.
Maybe they still find excitement in the real casino compares to online gambling. Or they really don't know if online gambling is available for them or not because they only see the real casino is the best place to gamble. We don't know what their reason to still play on the casino like on the picture. When gamblers decide to play whether, in a real casino or online gambling, they will choose what they think will give them satisfaction.
