Mary Reinemund, wife of Pepsico CEO Steven S. Reinemund, passive-aggressively buys Coca-Cola products whenever she is angry at her husband. 'Last Wednesday, Steve worked late on their anniversary,' said Bea Vance, the Reinemunds' housekeeper. 'Sure enough, the next day, there's a two-liter bottle of Diet Coke in the fridge.' Vance added that in the summer of 1999, during 'an especially rough time' in the Reinemunds' marriage, Mary was often seen wearing a promotional Sprite sun visor.
