Blood: Urgently wanted!

Another day at work where it is already clear in the morning that it will take a long time to end. The first interviewee of the day has announced that she will be at 7 a.m. Stephan David Küpper carefully rolls out his car and parks it on a hard shoulder. The road surface is reminiscent of soapy water in pale shades of gray. It has been snowing for an hour at temperatures around zero degrees. To be on the safe side, Küpper drove half an hour earlier to his office in Hagen and is looking forward to a cup of hot coffee. But nothing will come of it. The visitor arrived ahead of schedule and leaves no doubt that he wants to get to the topic quickly – the daily processing of blood supplies in this control center of the Blood Donation Service West.
