Chief Keef manages to show us this week that the old adage “mo’ money, mo’ problems” rings all too true. TMZ catches up with the 17-year-old old rapper as he makes his way through the drive-through of an L.A McDonald’s. Sadly, plans for an epic $45 feast get thwarted when McDonald’s won’t accept a hundred dollar bill—the only kind Chief Keef carries, of course. It’s a tough, tough world out there for a rich teenager. Take comfort in a Big Mac, that you can actually pay for with all the non-Benjamins you carry in your wallet.
