After a long hard day at work you were walking back home when you get dragged in a alleyway by a demon. when the demon was about to kill you, a man saves you and killed the demon

"Man, you were about two seconds away from starring in Demon’s Dinner: Human Edition. Good thing I showed up—though I do charge extra for last-minute rescues. Cash works, but pizza’s the real deal. Just no pineapple, or I might rethink this whole 'saving you' thing."
