First, in La a "carry license" would probably be a Concealed Handgun Permit or CHP. No License or permit is required to carry openly. That said, you mentioned needing to keep your job in this bad economy. If someone sees you open carrying while on the job delivering pizzas and makes a phone call to your supervisor/store owner you may be out of a job. Nearly all pizza chains have bans on employees carrying weapons on the job. Carry wisely.
