Yes, in my and other's experience it's very common for courier drivers to simply not bother and then claim they 'attempted' delivery. I know someone who was home and actually saw the courier stop briefly outside his house to chuck a card in his letterbox then drive off. Didn't even try ringing the bell. God knows why they think the few minutes saved in such a situation is worth risking their job over if they're caught.
We always have the same 60 year old delivery guy. He likes to talk to my wife. We never have any missed deliveries. Even if there is nobody home in the morning he swings by again in the afternoon. Huh.
