As others have said, delivery drivers don't read the delivery notes. I have automatic gates and I always add my gate code to the delivery notes.
Now, living in a regional/rural area I know my local delivery drivers quite well, and they know my gate code off the top of their heads, so no issues there. When I order from companies that use their own couriers, or not our local ones, they either throw the packages over my fence and leave or they will ring me asking for the code (I have a big sign out the front advertising my business and it has my phone number on it in big numbers, right next to the gate).
Usually they just throw my packages over the fence.
You matter, unless you are travelling at the speed of light. Then you energy.
