They should rotate their lunches so someone is there all day. I changed mail from plain s to paradise a month ago. No mail in a month. About ready to get ahold of my attorney. I use to get mail everyday. Now only two process in a month. Important papers are being waiting on and not getting bills

Why would the post office be closed when there is plenty of people to run it at lunch time. Makes it a pain in the ass when they close like this when there is no reason that they cant rotate to keep it open to the public.
