LOL. Gave a speech at a mid-sized company. Everything yet was digital (Invoice process, agreement, they got my digital slides.) and after the event I send them a digital bill. They replied, that they need the "original bill." I answered, that it will not get more original by letting me print it (instead of them) and send the bill to them, and offered/alowed, that they can print it (no porto, no CO2 transport costs). They just replied by saying: "We need the original bill." What???
