What discount percentage do first responders receive on Fridays?

First responders receive a 15% discount on Fridays at Denny's to honor their service and dedication to the community. This discount is part of Denny's initiative to support and thank those who work in emergency services, recognizing the important role they play in ensuring public safety. The choice of 15% strikes a balance between providing a meaningful appreciation for their hard work while also promoting customer loyalty and engagement. Other discount percentages are not established for first responders on Fridays, which makes 15% the correct and designated discount for this special occasion.
