Try Indira Gandhi airport at Delhi. (And no there is nothing racist in this post).

They won't even let you IN to the terminal if you're more than 2 hours before take off and they make you wait (and CHARGE you for waiting) in the crappiest waiting area opposite the main departures terminal that I've ever seen. There is nothing but those white patio chairs, people sleeping on their suitcases, a toilet, and nothing else. The boarding gates are small too.
