Uh-huh. Read it all before on various sites where disaffected people try to make out that somehow, they have a job that should be seen by the world as "special" and therefore need to make disparaging comments about the minority of the public who might make them earn their living.
If these people require adoration, perhaps they should try charity work or join the Army in a theatre of war? Those folk have something to complain about but generally don't.
The corollary, are those who enjoy their work and see it as a personal goal to deliver the service they are paid to provide. Fortunately, as evidenced by the majority of comments on these boards, there are more crew who aspire to that aim than the example in the post.
