Santa business? Just call it Christmas shopping like every other normal person. I'm pretty sure Gladys knows that Santa Claus didn't get her a gift. I guess Brutus could be talking a big present everyone receives on Christmas Day that they refer to as a "Santa present" but please, don't call it Santa business.
I wish I knew this guy's name because I swear if he's in one more strip, I will have to start adding him to the labels.
