What is full form of O.I.G.S. written on Indian Government post?

Oh, dude, the full form of O.I.G.S. on an Indian Government post stands for "Office of the Inspector General of Supplies." It's like the fancy title for the person in charge of making sure all the supplies are in check, you know, pens, papers, maybe even some chai. So, if you ever need a ruler or a stapler, you gotta go through the O.I.G.S. Like, they're the gatekeepers of the office supplies kingdom.
