OK. You were right. This is Dixie's fridge, and it was replenished every night. Clydesdale horse piss (Budweiser) for Dev, IceHouse for Dixie, and AmberBock for me.
In fact, the cashier at Albertson's started giving us some strange looks and actually asked of Devin: "Weren't you in here just yesterday buying this much beer?" I postulated that she was, in fact, the Grand Wizard (or whatever they call them) of the local branch of AA, and started humming "We're off to see the wizard!" every time the beer level in the fridge dropped to critical level.
