The delivery people are notoriously overworked and constantly in a hurry. But there are other alternatives.
For example, a service I like is Inpost. They have a few dozen of huge post boxes in each bigger city. About 20 compartments in each. The package is not delivered to your house, but instead you have 3 days to retrieve it from one of those huge yellow boxes. It's a little walk, but you can do it in the middle of the night (they text you with opening code). You don't even have to know the recipient's delivery address, just the phone number and e-mail, and the yellow box closest to them. So in a way it protects privacy.
