grazie42:I think this is one of those things that can be argued back and forth. I´d say that the problem with those dives is that they were "trust me dives", not that divers didn´t drop NDMs. If you do a dive (any dive) with your mind "switched off" you are inviting trouble, NDMs or no...
You feel that everyone should drop cookies and I don´t (though I´m open to the idea of changing my mind after I´ve gained some more experience) , I´d shalk it up to personal preference 11: ) and leave it at that...

Dropping cookies keeps the mind sharp! But you're right the thing to avoid is tuning out. Or getting mixed messages in the team.
