I have worked in a number of different sectors. I spent 4 years in Aviation.
Of all the different sectors that I have worked in, Aviation is the one with the worst customer service.
I suspect it comes from too many people in Aviation coming from a Civil Service &/or MoD background, or being trained/managed by someone with a Civil Service/MoD background.
The following is a typical response from some one in Aviation.
