You ever think how strict butler training is?
Like they frequently say they are not human while working, they are a butler instead.
And I heard someone failed their course because during the mock exercise they passed the paper to the lady of the houses secret lover, and apparently they were supposed to leave the paper nearby, as passing it to them acknowledged their existence.
Imagine the shit Alfred might have gone through.
Canonically, Alfred took the job in the wake of his father's death, per Jarvis Pennyworth's request
So imagine a 30-something-year-old Alfred diving straight into being a butler without a clue what to do
(actually, you don't have to. I wrote a fic about it here)
