 You leave the lab and no one knows that they're there. They're just these tubes. What are these tubes? They're just marked alpha. No one even knows what these tubes are. And meanwhile, literally someone, probably on your same floor, is trying to buy that same aliquot or trying to get an aliquot or trying to get a whole bottle of that antibody or that restriction enzyme or that buffer system. And so they're buying that new, where literally the refrigerator across the hallway has what they're looking for. But because they don't know it's there, you have this double waste problem.
