Mack

Marvel Universe
One individual named Mack was the proprietor of a diner off U.S. Route 66. He branded his establishment as the "Home of the Bottomless Cup of Coffee", even though he would warn his patrons of the dangers of excessive caffeine intake. One such customer that Mack lectured was Johnny Blaze. As the two spoke, an angel entered the diner and gave Johnny a silver bullet and a message to seek out Daimon Hellstrom. After which, he spontaneously combusted. Mack grabbed a fire extinguisher to put out the flames. A co-worker asked him if they should call someone, to which Mack replied, "Call who? To do what?"
