The steward mentioned that the photography that is not allowed is specifically "Shooting the Flight service"... meaning the steward and stewardess at work... that is touchy I guess.
I think it really depends who the Inflight Supervisor is and how flexible he/she is.
Aiyoh, I was just a harmless, incognito passenger taking photos. Didn't get myself drunk, nor walked all over the place in an unruly manner, disturbed the peace of other passengers, etc.
Anyway, I have a photo of him, albeit in the background, gesturing to stop me from taking photos. Will post it later.
