Some people get a little too comfortable on airplanes. I once saw a woman trimming her hair on the plane. I've seen a someone trimming their nails and i've even seen someone painting their nails. A big no no because of the smell (and yes the flight attendant stopped them).
Here are some of the rudest things someone can do on an airplane:
- Fully reclining your seat
- Taking your shoes off
- Using the overhead bins at the front of the plane, when you're not sitting there
