Greenbriar Mall Office Office

As post offices go, this one is not too bad.
They open at 10am and close at 8pm — Monday — Saturday. They are closed on Sunday, and have a gated entrance, so there is no way to buy stamps or other postal services once they are closed.
This place is always packed during the lunch hour and around the first of the month.
The staff has probably worked for the postal service so long, that they are just immune to being nice or overly friendly, but they will get your packages mailed out correctly, so I can live without chit chat and fake smiles, and appreciate that they work quickly to get the lines down quickly.
Mail is picked up at 5pm to go over to the main post office for shipping and processing.
