Has anyone of you guys come across any of the situations listed below ?
Yes I have. The chap in question was one of the ex-Cathay 49'ers and simply refused to follow our SOP's and got very dirty when you didn't follow whatever ones he was doing.
I didn't know what he was doing far too much of the time and went into the office and told them I was refusing to fly with him. I was perhaps more disappointed that he passed the sim rides and was allowed on the line without being corrected.
