Any trading or bartering with prisoners by any person associated with the operation of a county jail or a county penitentiary is strictly prohibited. No sheriff, warden or superintendent or any officer in charge, or any staff person shall receive a gift of any nature whatsoever from any prisoner, nor shall any person in charge, or any employee, be permitted to give anything whatsoever to a prisoner, or to buy anything from or sell anything to a prisoner, or to extend to a prisoner any favor of diet, clothing or of any other nature not common to all. These same prohibitions apply to relatives or friends of prisoners or to any other person acting in behalf of a prisoner.
