I see far more problems with pax than with the crew. The J pax who decides to stand up and get something from his luggage when we're still obviously in ascent and the FAs are still strapped in is one of my biggest pet peeves.

Then the pax that obviously ignore when the FAs get on the speaker and tell them to sit down. Seriously, that blows my mind.

Yes, sometimes the seatbelt light stays on too long. But if the FAs are still strapped in, that should be a good sign that you shouldn't move.

I don't really notice too many problems on securing the cabin prior to landing though.
