Of all the things people do on airplanes...this might be one of the most egregious offenses.
In the video below, a passenger films his seat-mate as she clips her nails mid-air. This is not up for debate. Is it ok to clip your nails on a flight? I think we all know that those suckers can go flying just about anywhere. What if you were eating or drinking? Could this person maybe have taken a trip to the bathroom? Maybe even taken care of this in the lavatory in the airport?
Do you wait until you get onto a flight to trim your nails?
