BJ’s and Florida Statute
Your question as to how to enforce the Florida Statute against BJ’s is easily answered: Do it yourself.
Contrary to accepted belief, a criminal statute also gives grounds for a civil suit. It would appear to me that that employee has been damaged — the usual grounds for a civil suit — in a certain amount. And of course there should be demand for an injunction against BJs prohibiting them from continuing violation of the Florida Statute.
Also, in most States, a lawyer can get permission from the local prosecuting attorney to file a criminal action personally. In fact, most prosecuting attorneys would welcome other attorneys coming in and helping clear off his/her desk.
The law(s) are written for everybody, not just a select few. It’s time we become the "select few" the laws are written for.
