It's sad to see how foreigners are deceived there. As when I've been there how silly to see that when purchasing a flight ticket I've been told that there exist residential as well as non residential tickets. I was supposed to pay nearly thrice the price of a flight ticket because I was a foreigner. Is it that when a residential people buy a ticket the plane flies with water as petrol or for foreigners the cost of petrol is excessive? I think it's a way to discourage tourism to come there by this stupid way of purchasing flight ticket there.
