i think you got bad info
the same thing happened to me. GA insisted I pay the SB fee to be put on the list but I knew there were plenty of seats so I wouldn't ante up. GA wouldn't put me on the list. So I thanked her for her time and went into the PC and asked an agent there. Agent was incredulous that the GA wouldn't comply and gave me a BP. Imagine the GA's surprise when I wandered up to board just before closing. "Oh - you got on" she says. I just smiled and said -"yeah - lucky me!" Lesson learned right here on FT. thanks everyone
