We have "Porch Thieves". I have a retaining wall packages can be hid behind.
Instead, I find packages out in the open in the center of the walkway.
It must be true that you only have to have the IQ of a ping pong ball to work delivery, or the drivers have told friends to follow them and split the booty.
Either way, the supervisor of delivery should be taken out back and shot.
Either way, this old Marine is locked and loaded for Porch Thieves.
