The driver knocked lightly on the door. Luckily I was in the hall and answered the door immediately. The driver was halfway back to his van with my parcel that needed signing for. If I had been upstairs or outside I would not have heard the knock and I would have missed this delivery. Is it too much to ask for a driver to wait to see if someone answers before making their way back to their van. I can only assume this is a tactic they employ to move through deliveries quickly. It certainly doesn’t have a focus on the customer.
