Snake, I don't think anyone would really disagree with what you say. And that I believe is what the spirit of the missive was "meant" to be. But that is not what his words said. It should not be up to us to try and interpret what a man in his position is trying to convey. Maybe I should try and interpret what the OM-A says. How's that going to work out.
First he says eating or drinking whist in uniform. Not while transiting the terminal or whatever, simply eating or drinking in uniform. Next comes NOTHING boarded for the passengers is to be used......That implies to me everything; soft drinks, coffee, tea, leftover rolls or whatever. That's what the gentleman said. So imagine if this email gets to some grade 2. How do they interpret it? You tell me.
Words have meaning. You are interpreting his intention just like some CC might. Who's to say who is right?
