I think when you're flying you're probably gonna get a bad passenger. On long haul flights it can be unavoidable really.

On my way from Doha to London, the guy behind me kept putting his sockless feet on my arm rest and like, scratching my arms with his LONG ASS TOENAILS. I also had my hair up in a ponytail and everytime he stood up (which was a lot ) he would hoist himself up using the back of my seat and he kept yanking on my ponytail really smurfing hard!

I also overheard another passenger shouting at him because he was staring at him while he slept... Creeeeppppyyyy. He got taken off the plane by the police when we landed. :/ That's probably the worst one I have.

Honestly, on a long haul flight I'm probably a pretty horrible person too. If I fall asleep I'm likely to sprawl out and end up touching the person next to me by accident or something. I try and be as considerate as possible on a long haul flight but little annoying things can be unavoidable. There's no need to invade people's privacy in this way though, it's ridiculous. Can't go anywhere now without fear that someone will snap your picture for something you do just as you're going about your daily life...
