I am not very much familiar in gambling casinos but there should be an attending physician to check if any one of those people gambling in their vicinity will show bad symptoms of excessive gambling, that guy has little support coming from his family, they should have seen the first sign if the guy is gambling excessively.
Why would any gambling site care if any gambler is addicted or doing more gambling ? Remember that running a gambling casino is a business (and it is not a social welfare program) and the sites will never implement anything which may decrease their revenue.
