Fortunately the ****heads in the 75/767 left seat are the minority however they are more than likely buds with the chief or are check airman, or at least that is the way it worked in ORD. One CKA in particular has a sever Napoleonic complex and loves to ride FO's as I witnessed on a couple of international trips. When asked the FO being checked just shrugged it off, pretty big of him if you ask me. Flew with a captain that actually complied with my stupid, out of sequence request for flap retraction on approach to ORD, at the end of a very long international trip. It was obviously a mistake on my part but instead of questioning me he retracted the flaps, laughed and then asked what I was doing, making me feel embarrassed at first but ****ed off later. But again you are dealing with a guy with an air of arrogance that is obvious to all, yet another bud of the chief.
