Robbiee,
You miss the point altogether.....it is not your job that depends upon it....but rather your life and that of your passengers.
Doing something safely and within the limits set forth by your OpSpecs, FAR's, and Company SOP's does not in any way suggest being "cavalier".
I have refused to fly in weather that met the letter of the law and rule...because it exceeded my personal limits.
I am sure all professional pilots with any experience in the business have done that....as they well should.
