Any postal workers on the board? Got a question or two...

So, even though the post office policy is they deliver up to 70 lbs, the carrier can just decide they don't feel like delivering the package?

Pretty much. I had a package due to arrive, and it was just a small package.

The delivery lady decided she was going to take it back to the PO and mark it as "no safe place to leave it".

We had just got over a huge snow storm, the roads were open, no problem getting around. My wife and I were outside doing clean up and watched her drive down the road right past us and never stopped.

So she just decided she didn't want to stop.
