I live in town, actually on a sidewalk, mail delivery is generally good. I even warn the regular carrier that a "heavy package" is on the way.
He isn't perfect, last month I got a double bill with one month's charges marked overdue. I looked back through my checkbook and sure enough, I had not paid them the previous month. I figured I had discarded the bill with junk mail and sent in the double payment. But then I got an envelope from the next door neighbor written on "So sorry, we did not realize it wasn't ours and opened it. We did not read it." But they had sat on it for a month.
