Thanks, DCA Blondie, that sounds like just the ticket!
Jet flight is so smooth - most of the time! - and we have so many aids (Doppler radar, etc.) to help avoid dealing with wind shears, etc. people have little experience with nasty bumps in the night, and feel FAs are just carping when they ask people to stow that laptop or big bag.
I've been in landings hard enough to pop all the 02 masks and open some of the bins; I'm glad nothing large went flying inside the cabin. And all it takes is one incident like AF 358 to think of what could have happened if an exit was blocked by a bag, etc.
