Sounds like she was trying to make light of needing you to volunteer after all. Had you spoken with the gate agent at all before boarding to see how likely you'd be needed as a volunteer? One can always turn down being a volunteer even though one's clicked in the app for a specific dollar amount bid. That stinks about them messing up your flight. Was it a location where you were volunteering where there was an admirals club? cuz I certainly would have just taken care of it there if it was going to take so long to fix it.
