You don't have to flat out accept it either. You have pro-standards. Thing is, a big part of being a good FO, is learning to be a chameleon. Know your stuff, do a good job, and realize there is a big difference between technique, and procedure.

Just because the other guy, or gal might not do it the way you would, doesn't mean they are doing it wrong. As painful as it may be, some of the stories you hear may be good. You might even learn some useful information, no matter what seat you are sitting in.

The pilots you fly with may not have your experiences, but you might be able to learn from them. I make it a priority take something away from every flight, and every one I fly with, Good or bad.
