I had 14 packages for a business (Vector Marketing----they sell Cutco knives) that was relocating to a new address on my area. When I got to the delivery stop there was a key in the door but there was no one in the office. There were office supplies for the staff and tools being used by the contractors for the renovation so I knew that I was at the right address. At this point I had a decision to make-----do I leave the packages and make sure that the door is locked on my way out or do I leave a delivery notice and deal with the same 14 packages tomorrow? I decided to deliver the packages and made sure that I locked the door behind me. To answer your question, yes, I signed for the delivery.
