I once had a f/c pax who spent the first half of the flight picking his nose and flicking the boogers in the aisle. That was so successful he decided to use the last half of the flight picking his teeth with the same finger. I was so grossed out, I was almost dry heaving in the aisle. Upon arrival in _ _ _, I asked the agent if she knew this passenger. She said, "Yes, he's one of our top EP's!"
