The oft asked question is, if Denny's is always open, why are there locks on the doors?
Michael Lasiter of Modesto, CA, had been injecting cocaine and thought he had accidently injected air into his vein, which can lead to death. Believing that if he cut his arm off he would save his life, he ran from his motel room to a nearby Denny's, grabbed a butter knife and started stabbing himself in the bicep. When that didn't work he ran into the kitchen and started using a butcher knife. Police arrived and used a Taser to subdue him. He was taken to a hospital.
Denny's closed for the night to clean up.
