i was jumpseating out of DFW last weekend and their was a lot of people milling around. i wasn't sure where the employee line was so i went up to this one tsa guy who was standing against a wall just watching ppl standing in line. i said politely" Sir excuse me I have a question...." and he cut me off and was like Sir I cannot help you. I was like I'm just looking for the employee line, I'm a pilot and he just stared ahead and wouldn't say anything. I went back and stood in line for another 10 minutes bc i just wanted to get home. i watched him standing there, on duty, text messaging someone on his cell phone.
