re: Whataburger, Wendy's, and Sonic bugers: fresh or frozen?

I'm not sure about the patty handling practices at run of the mill Sonics. However the Rayvegas Sonic located in beautiful, sunny downtown Rayvegas does NOT use frozen patties. Furthermore, the fingers and hands of the highly trained Brazilian beef masseuses that RVegas Sonic employees to deep tissue massage their certified angus wagu kobe cattle are warmed to a pleasent 107 degrees to ensure maximum bovine peacefulness during its final days.
