 Many franchises opposed the extensions on multiple grounds ; operators claimed employee and customer safety was jeopardized by the extended hours , with several Miami @-@ area franchises noting incidents in 2006 and 2007 where staff or customers were killed during extended hours . Additionally it was claimed that the extended hours were not profitable due increased costs associated with operating the locations at times with lower customer traffic and subsequent lower sales . Franchises and the NFA noted the franchise agreement only required locations to be open until 11 : 00pm and did not contain riders that allowed the corporate parent to amend the agreement . In response to the changes , three Miami @-@ area franchise filed a suit in July 2008 with the Eleventh Judicial Circuit Court of Florida in Miami to stop the change and force the company to make it optional instead of required . The NFA issued a statement that it " unequivocally supported " the suit , and that " ... the franchisor does not have the enforceable right to mandate extended hours . "
