This is my second favourite area at the Post Office:
The staff there knows me already as I regularly come see her to buy postcards and philately stuff. Also, she was nice enough to hand-stamp my postcards last December 12, when the main counter at the PO where you buy stamps refused to do so. You see, the 12-12-12 postmark is an auspicious one and many collectors the world over have been swapping for postcards and covers bearing this. It will never happen again in our lifetime so this is considered valuable.
Oh, and in case you are wondering what’s my most favourite area at the PO, it’s the hallway where all the post boxes are located, including mine 🙂
