I didn't show commercial considerations, basically he said I didn't treat him enough like a passenger and as such he could see I could fly safely
Seems a tad harsh... I guess each ATO is different... I've heard of some who are lenient and others who will get you at anything they can find.
As for your situation Ixixly... that 'treatment of pax at a cpl level', is that even part of one of the boxes the ATO has to tick off during the test? (I cant remember)
