I had the USPS drop a box over the fence before and leave a box on top of the mailbox by the road.
*shakes head*
My USPS friend does rural delivery.
She is allowed/paid a total of 8 seconds to drive up a driveway, get out of the vehicle, go to the door, knock, wait, leave the package or a note and get back in the car, go back down the driveway and continue on.
Anything beyond that 8 seconds is on her own time.
