I have to agree that it's pretty unprofessional to stand in the public area and not work. If that TSO was on break, then he should have gone to either a designated break area or away from the work area. Hate to say this, but I think he was probably a supervisor based on his stereotypical stance. Unfortunately, the video quality was poor, so it was difficult to see the shoulder boards.
By the way, there's another clip titled "Going in Circles" that's pretty funny. What the TSOs are doing is calibrating a WTMD, but it's great for laughs.
