I had an agent one day tell me I wasn't on the list when I asked for a seat request card because I checked in on my phone. I responded that I was listed and on the screen in the gate area. She then said I was not and that she didn't have time to list me about (about 40 prior to departure and no one else in line). She reluctantly pulled up the list when I asked politely to see it. I walked around the counter, pointed myself out and she then printed it off/threw it at me without saying a word. She needed to take a nap or something
