That instructor is confusing himself with being a checker and is above his station in life. If I'm not mistaken the same chap at the end of an RT with time to spare offered any free exercise time to try anything. Well it all went pear shaped! Exercise requested wasn't as he liked and said non jeopardy play time ended up with a visit to training office and later to CP. NEVER miss an opportunity to say no, or nothing!! Sad isn't it. Best of the best of the best.
Now about those riverts?
