I'm quite shocked at this, are there really people out there like that?
In the fullness of time I'd like to fly for an airline, but at the moment I'm an FI. I love it. I get a thrill when ever I teach something and the student suddenly clicks and it works like clockwork.
What is a professional? Someone who applies the same attitude to every job they do.
I'm teaching at the club where I did my PPL, and the current CFI (and owner) is the instructor who taught me. My approach to flying, teaching flying and my "other" job has always been the same, professional, fortunately he recogised that and I walked into an instructing job.
Attitude in the aircraft is key, but the attitude of a prospective employee is also key.
Listen well to shower of sparks, and learn.
