 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 in your same floor is trying to buy that same aliquot or try to getting 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 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.
