"Sir, can you read? Your bag can't go through. Place it on the table. Sir, I can't open it. You have to open it. Are you going to open it or hold up the thirty people in line? There's another pocket on that bag. You have to open that too. Now, take out its contents. There. Now, that wasn't so hard was it? Next."
"Do I need to take out the contents of my bag for you?"
"No, go right through."
