True, though I guess on occasions the cabin crew can get a bit busy and forget to check their watches..
Anyhow some types have a "pilot intervention" alert or similar if no button pressing/switch selection is done for a set period of time..
Might have been "fatigue", could just a likely been volumes on the ACP turned down for some reason....
