Another Post Office Rant

Just back from my PO box, which contained two notices that I'd received Express Mail.

Came home and phoned the post office. Why did I get notices instead of my Express Mail?

Express mail requires a signature for delivery.

Ummmm, I'm not available 24/7 to sign for mail put in my PO box. So, I should tell people not to send me Express Mail because I can't get it at my PO box?

Oh, no. All I had to do was stand in line at the customer service desk and pick it up (the line was more than 20 people long).

Attention all of you who send Express Mail to PO boxes: the recipients may, or may not, get it.
