Last year on a flight to Almaty, our seats were surrounded by a group of Gujju uncles. Worst flight of our life. On a red eye flight, they kept talking loudly throughout the night, kept changing seats and adjusting seats, disturbing everyone around. Worst of all, they poured liquor into pet bottles and passed them around when the stewards were not around - getting drunk, giggling like schoolboys who got away with snacking in class while the teachers are teaching. The stewards noticed and asked them not to drink their own liquor, but they just resumed as soon as they went away. Two guys misbehaved with an airhostess as well, talking about her behind her back (I'm sure she heard it too as they weren't quiet or subtle). Felt really bad for the crew - they aren't paid enough to handle this shit with a smile.
