They make that little sound of superiority..."Hmph!...I like to keep my bread fresh."
I think they're just being anal. Maybe I'm jealous of their ability to retain and make full and proper use of their leaventethers. After I make a sandwich, I can never find the damned thing. So, I have to smoosh the bread down, to the bottom of the bag, squeeze out all the air, twirl the plastic around, and fold it under the loaf of bread, before I put it back in the fridge."
