Admittedly, I am not following this story closely. However, if I heard the report correctly from another room, the proposed legislation has already been changed, from the original proposal, to apply to new leases with the authority and Chick-Fil-A has a very long lease...like 30 years.
Basically a move to grab attention, and (IMO) an overstep of authority. A legislature doesn't have the authority to mandate business hours.
