India Post — Demand for cash for handing over passport

Address:

110092

At around 2.20 pm today, postman on duty in lakshmi nagar delhi -92 came to deliver two passports, one in my name and another in my husband's name. Shamefully, he demanded rs 500/- for two passports. My husband who is at home due to illness denied but the postman shamefully said he will take it back if money not paid and we will have to appear in the head post office to claim it. He threatened that he will destroy the passports which will leave us running pillar to post for claiming it. Ultimately my husband had to give him rs. 500/- to get the passports.

What kind of system is this? Is it like a lottery or a jack pot for which the post man is obliging us so demanding cash for delivery?
