I often wonder how the post office stays in business. Amazing how that works. Ever get a box that has been crushed? It happens to me most of the time. I don't think it is the locals though. Nice people.

If you require an ID for a small credit card purchase under 10.00 then there should be some sort of sign displayed. My card is a chipped card with a pin assigned to it. I should not be asked for my ID. Especially if I have at least two boxes with the name of the card written on them, or the fact that I am a local with my employee shirt and name tag on. Really people, the fact that I wait in line for a long time then have to wait again for not having my ID on me for a small purchase is just dumb! When in reality the Post Office needs to upgrade their card readers so I can use my credit card with my pin and shouldn't have to go get my ID. Uhg.

I have constantly complained to John, the manager, multiple times about my mail getting lost or not forwarded. It has been a waste of my time. Today, I got a delinquent notice to from the power company and almost had my power turned off because my electric bill was lost in the mail.

SOMETIMES WE PUT UP THE RED FLAG FOR OUTGOING MAIL AND THE CARRIER DOES NOT PICK IT UP. IT HAS HAPPENED IN THE PAST AND IT HAPPENED ON FRIDAY AND SATURDAY OF THIS LAST WEEK 3-20-15 AND 3-21-15 I HAVE TRIED CONTACTING THE POST OFFICE BUT NO ONE HAS PICKED UP THE PHONE DESPITE SEVERAL ATTEMPTS TO MAKE CONTACT. HOW SHOULD I DIRECT MY REQUEST AND CONCERN ABOUT THIS MATTER? IS THIS THE PREFERED METHOD NOW?

I've been receiving mail at our companies PO box at the Key Largo branch, and was told I need to bring in a couple of forms of ID to continue getting mail there. I assume one is the Driver's License, what is the other?
