Something tells me Lucifer is obsessed with Costco (/devildom equivalent). It's his Disney world. He can buy anything there, no time wasted. He likes to sample things and even treats himself to a lil ol' hot dog. Returns are a breeze. Beel has food for days, his family is taken care of. He's the guy that buys the 27 pound bucket of mac n cheese every week. The reason he's so fit is bc of all that lifting at Costco.
