What can I say about a post office?
I usually do shipping from UPS as I have a pick up service that comes to my home. I ended up getting a P.O. Box here. I didn't know if I was going to be moving and needed a concrete place to get my mail. I hate filling out a change of address form. Plus, you can put your mail on hold if you go out of town, and they will hold your packages. I had friendly service when I set up my small P.O. Box and was given a run through on how things worked.
So, it's just a part of life. No problems but no expectations either.
