i think so long as an experienced divers wishes are communicated prior to crunch time there will hardly ever be a problem. Joe Dive Master doesn't care whether you put your fins on at the bench, at the gate, whether he does it for ya, or whether you would rather hit the water and put your fins on there. So long as its discussed before hand, and so long as it doesn't pose a danger to you or anyone else on the charter, its good..
