There are many options available in india to buy and sell the bitcoins so there is no need to meet someone in personal and risk your money and life in danger. This person could be a scammer or he may have the intentions to harm the buyer and run away with the money. If someone don't wish to use the local exchanges then he can also use localbitcoins.com to liquidate the coins. So it is not advisable to meet the unknown people as we don't know their background, precautions are always better.
some people are trading in cash just for saving taxes , lol .
if you succeed in saving tax today then in future it will be exposed any day , no benefit to do it if you main motto is saving tax .
and if not , then you can buy from exchanges .
