I get this thing with the hands is a "thing"…
I've done that for as long as I can remember to avoid sweaty palms, I even stand around like Napoleon w/my hand in shirt.
Inversely, I'll admit, at times I've been given rock-star treatment in the military by some high ranking officers whom I didn't care for.
I assumed, it was because I was sharp in my uniform/great at my job. Now you bastards have me wondering if it was nothing more than my body peculiar body language all along.
