Ixixly can you please elaborate on commercial considerations. It sounds like the examiner was expecting pre take off refreshment followed by a hot towel, then tea/coffee and a news paper or inflight magazine.
For the examiner to say that you didn't treat him enough like a pax, what was the examiners expectations of how a pax is to be treated, and where in the test performa does it state such expectations. What I am getting at is it sounds like your examiner was a bit of a p$%#k
It has been a while since I did my CPL but it is interesting to read what is expected from candidates today.
