Peek behind the scenes in a postal office

Another trip to the post office; it felt like a trip back in time. In this age of technology, looking at so many letters and papers, this place made me wonder what is their sorting system, how do they manage to keep things in order and tracked. The trip this time, to mail our correspondance to various places around the world. It is interesting to see the way they work in the office and how important mail still is in this world. On this visit the postal service even had 20 ruppee stamps!
