I did a crew up with an SO in the sim and saw him flying with one hand. I informed him that we fly boeing big jets with both hands, except when needed for the thrust levers. That was it. I didn't send a letter whining about it to the fleet office.
There are a couple captains at CX that seem to go to the fleet office about EVERY detail they encounter. My how the fleet office must feel like babysitters. One personality conflict does not require a write-up in the newsletter. Certainly there are more important things!
