I had post #37 in mind:
'It can take the CC a long time, from the receipt of a command to secure the cabin, to complete the task. The most compelling evidence I've seen that they had not completed that task was the excellent picture posted by
Shadoko,
here, of one of the galley catering-cannister stowage units. The latches that must be closed to secure the cannisters are plainly open. Any proximate cabin crew member worth his/her salt would have secured them before sitting down, if severe turbulence was expected. '
with apologies to CS.
