Same with me... well, there was one quite friendly and helpful guy on the lounge entrance who helped me tracking my transfer bags with AA. But when I went back to find him again to get an update, he had gone, so I asked his colleague... who snapped at me and suggested I ask the original guy instead but she had no idea where he had gone.
My usual experience in the USA to be honest, if they're not working the fake customer service thing to get tips.
