Has there ever been a story that describes how Alfred came to work for the Waynes, or why he was close enough to the family to have been left custody of Bruce?
Pre-Crisis he showed up after Bruce became Batman. I think his father worked for the Waynes previously. Batman Year One
introduced Alfred as the "old family retainer". (IIRC) I don't recall if Alfred was ever established as Bruce Wayne's legal guardian. At best he was just a father-figure and confidant for the young Bruce Wayne.
