Some gamblers can be like that but I do not see gambling as a way to be looking for bonuses. What I need from casinos and other gambling sites are good customers service and good services in a way I will not complain at all. That is why I prefer to stay  more with gambling sites that give good services. But I noticed people like bonuses, that is why you will see new casinos with good marketing with customers get more on the casinos which are attracted with better bonus offers.
