Be advised USPS as of 08NOV14 - carriers who sub for reg delivery person are stopping by only to collect mail as flagged but they have demonstrated over the past three days to not deliver anything. Is this the new standard? Where are my bills that normally come? They pull into the cul de sac, eval the flags, then scoot.
