This is exactly the attitude that I am talking about. You make yourself sound as if you are too good to be in the same room as a flight attendent. Attitudes like that are not welcomed on any team, and that may be the thing that they are trying to see. Just like asking how would you feel about a woman captain. They want to see your reaction, and the high and mighty thing probably won't go over well. It isn't as if the FA or "bag thrower" is actually making the hire decision, but talking down to them like they don't even deserve to be speaking to you, would most certainly make the decision easier for the people who are.
