So you are sitting in F and working on your laptop they guy in front of you puts his seat back at full force and whacks your laptop screen.

Should you be upset (this is F and supposedly these people should realize that someone may be working behind them)?

I have a vision that some day they will catch the top of the laptop just right and pop the screen out in the process.

To me it's just common sense, don't shove your seat back at full force as quickly as possible.
