I have left flying, and the rigid adherence to Standard Operating Procedures, and the all important Flight Crew Orders, but have moved to another job that the rules, and protocols that I work to actually affect whether someone lives or dies, and are not mostly just the whim of some killjoys.
All I was saying earlier was that you either follow like a lemming without thinking and reasoning why everything that you are told to do, or you think and have reasons why you want to do something.
For the record, I do not smoke, but didn't care whether people did when on turnaround, if the fueling had finished, and the crew weren't seen by ground staff.
