You know, the main thing I ever did was to try and make things easier. We would have the bird nice and toasty on those cold days, things clean and belts ready for simple strapping in. We put a hook on the back of the pilot seat for the FE to hang his bag off of.
One thing we always did was to strap in the chalks for the Load while he was outside doing engine start. Whatever we could do we would, and it usually payed off. Once while broke in Turkey for a valve housing change the AC bought us lunch and delivered it to us. Back in the day when I worked fighters, the only ones who would help out when you were working your a$$ off were other crewchiefs. I didn't even experience the "Herky lovin'" when I was on tankers, which was supposed to be a tight crew.
I miss the Herk. Good times.
