I'm familiar with all of the aforementioned "quirks".
We had a CO in the late 70's who insisted that the brothers wear only white shirts, especially when giving parts.
His son visited our Circuit Assy, and was picked up at the airport and brought directly to the Assy, and then had an interview on the program. Guess what? Yeah--and it was DARK too.
Well, this CO didn't say another word ever about white shirts. He was a pretty nice guy all things considered, in New Braunfels Texas if I remember correctly.
