to paraphrase famous ad: "can you hear it now?" !!

Pax will be in line, phone to ear, telling TSA, "sorry, I need to finish this call."
TSA--"sure, sir, no problem, just step over there."
Pax-- "ok, I'm ready."
TSA, "sorry, sir, you'll have to go the back of the line."
Argument ensues, YouTube has it and it's all over the news even BBC...
