Does not wear baseball caps!
A professional pilot knows the relationship between profit and safety and strives to get the balance right.
And, he does not wear a baseball cap on the flight deck! About a year ago, whilst standing on the apron at Esperance, I saw a Skywest F50 First Officer don a baseball cap after taking his seat. To his credit, he did not wear it backwards. I very nearly wrote a little letter to the airline about that.
