Attitude is key..........
After over ten years of PCs, I've noticed some things never change. A check airman's demeanor coming out of a so-so oral is a definite sign of trouble. If they perceive a lack of preparation for the big event, or have to work at getting the answers from you, their virtue of patience is wearing thin. Maybe your oral wasn't as smooth as you thought (or your check airman is wound real tight). Retraining for some events during the PC, followed by immediate and hopefully successful demonstration of a maneuver is quite common (especially for stall demos and v1 cuts.) Lack of clear adherance to published profiles is a worse sin than simple rust or sloppiness (I've probably seen it all).
I am fortunate to only be a line check airman and only visit the rocking closet twice a year. I always leave the sim resolving to prepare more thoroughly next time.......................
(I also still wear a tie to all checking events out of respect for the event and check airman, couldn't hurt.)
