In my experience, the guys who preach from the pulpit about shiny shoes and hat regulations, are the same guys who answer the phone on their day off, accept every roster violation without a whimper, are desperately crawling up management's ass for the next DFO job, and still think they're the most smoking hot "professionals" on earth.
Give me a guy in flip flops and baseball cap, as long as he knows how to fly a jet, work as a team, and doesn't do my head in when I have to sit next to him for 12 hours
