You’d never know. Trust me.If it wasn’t in my FOM or the FA version of their FOM, I’d put an end to that. Not on ma plane you don’t just go inventing rules that aren’t the norm. At VX we never locked lavs. I got my routine, 10 prior to push I make the welcome aboard PA from the galley handset (come at me bro ) and then hit the pre-departure lav. No problem at VX, but at AS I notice the lav is locked by then. No big deal, the FA says no one in there so I just unlock and go. Messin up my routine
Wait until you’re in your 40’s when the new(-ish) captain sheen wears off. There are things you concern yourself with and things that you do not and, at the end of the day, “How Much Do You Like Paperwork?” because nothing will change.
I tell all my new captain friends that complain about FCR’s and ASAPs. “If you really want to practice penmanship and your clerical pool skills and get little to no feedback in return, know yourself out”.
