Good point Stirling.
I would not imagine all pilots coming to ops desk asking for changings or different kind of needs. Standardization is what can save us all, since as we say in Italy: "some wants it rare, some wants it well done...". Of course we cannot provide customized briefings, according to whom is going to receive them (our rep in Mexico have a picture of each cpt, and according who's coming they assume different attitude

it's a joke, but not too far from reality...).
It is indeed necessary that flying crews report what is wrong or what could be improved, but following the company's line of responsability. Then reports are discussed, and when a change is considered applicable, it is applied to the whole community.
Our pilots, when leaving from the homebase are briefed by dispatchers, but when leaving from outstations they just receive a stack of paper without meeting us. They normally operate the same, then I guess a physical meeting is not actually necessary.
Ciao
