My beer fridge is typically kept in a full state, even if the beer does occasionally share space with other food stuffs. (Amazingly, I do occasionally find myself staring at the full fridge and not seeing something I want to drink.) Friends who visit know they are welcome to help themselves to whatever is in the fridge. Fortunately, nothing really special has ever ben consumed inadvertently, though I have worried about that in the past.
I've recently learned of the "camouflager" for hiding those special bottles from casual browsers. Check out this video.
