In my neighborhood the post guy won't bring ANYTHING that's not standard. If it's a package or a registered letter, he just sticks one of those "we missed you" slips in the box. He never attempts to deliver it. His asshole answer when you ask him about it is.."they don't give me those items". Which is total BS, since the route guys are required to sort their own mail before going out. He's just a lazy ass.
