Playing for fun is the initial expectation from every gambler to do, so that we don't get ourselves into other things else beyond our capacity at the cause of gambling, also, our irresponsible gambling nature does not make any difference to the casinos if we choose to be a responsible gambler or not, it does not affect them either way, but we are the one being affected, because we will be missing out on other things so important in life we could have enjoyed, if we are a responsible kind of gambler.
