I've been to this shop. Interestingly, his 'new' business is also something of a relic of the past. At some point in history the post office in Panjim started insisting that it is mandatory for international packages to be sewn into a linen enclosure to protect the package. I remember this being a common practice a few decades ago everywhere in India but I haven't seen anyone do this in Delhi or Mumbai for at least the last 20 years. Yet it continues to be 'mandatory' here, and he has a monopoly on serving this market.
