More controllers should visit cockpits on black hairy congested nights as part of their training (not the morning jam runs).
I fully agree - however, in the current political climate, this is much easier said than done. Like RAAFASA, I have often jump seated, whenever available, be it as slf or on training/mail flights/sim checks and always find it fruitful.
In the same vane, I believe it should be compulsory for CPL holders to visit a busy ATC unit on occasion - again not during the regular lulls in traffic but when it's busy. I believe that this would be a huge eye-opener for many. Going by your monotonously regular derogatory comments, I assume that you are one of those that considers this completely unnecessary, as you appear to know it all already!
