Got another one~
Wife and I were fiying out of VIE from a friend's wedding this Jan. And for those of you been there, you probably remember they have the luggage "wrapping" service for 8euros. A russian dude wrapped it, and later found out he needed something, apparently clueless, he asked the person wrapping it to "unwrap" it, and got really upset when he couldn't get his money back...
and the VERY same dude, who was with a family, had about 4-5 pieces of medium size luggages (they were too big for overhead bin anyways), walked straight to the security point, and when the securities asked them to go to the counter to check it in, they were clueless. Not much of a scene, but the look on their face was pretty funny, like a baby eyes wide-opened, looking at you. Haha.
