Sorry Boys but I'm going to trump this if you do not mind me intruding here on CO forum.

Fingernails? Consider yourself lucky. I had someone clipping their toenails in First Class (Fingernails I've had too many - its painting them that drives the flight Deck mad when the fumes trip the alarms).

On this occasion (BA but First is First and I would expect better on a Greyhound bus frankly)In one instance a piece flew off and landed - plop - in someone's drink. I was in the galley and did not see this until I saw something fly thought the air and cross the aisle

The someone whose drink it was was distinctly not amused and neither was I who happened to be working there. His political views I will never know but his neck was well and truly red when I had finished with him.

I really do not know why it is that air travel seems to be a magnet for every slob and every lunatic going.
