Dixons! I am with you on this one, well said!
It seems that sometimes nobody is responsible except us... One little thing goes wrong and you are suspended or under scrutiny of some comittee, and you could loose your job.
I waited 1 week ago 40mn after ETD with all passengers on board, because some ground staff lost the pax manifest and we had to wait forever to get a new one.
Apply that simple rule to get better OTP: Push ground staff to close the boarding gate ETD-10 (as per the book by the way), whoever is lost in the terminal, and start offloading the missing one ASAP, you might end up going on time and passenger will learn to be on time too...
