Our carrier sucks.....we've had them refuse to leave our mail because our car was parked on the street............ON THE OTHER SIDE OF THE DRIVEWAY FROM THE MAILBOX...claiming it was in the way. Also had them say they couldn't get the mail truck to the mailbox because "grass clippings were obstructing access to the mailbox" (keep in mind, this was not even a "pile" of grass clippings, but just where I'd edged our curb an hour earlier and hadn't gotten to blowing the clippings away yet.)

Never underestimate how hard lazy people will work to avoid doing their job, even when the job itself would've taken less effort.
