Honestly no idea. My first time EVER with it. It was a busy airport, and as an over 40 year old, white, blonde, green eyed woman I was probably more flustered and confused than anything so I may have missed something. The lady who did treated me like I was a you-know-what. Unbelievably rude and brusque. The second lady was a bit better. I was not asked if I wanted to move to a more private screening so it was visible to God and man at Terminal 4 at JFK. The second one was behind closed doors as I said, but all of my personal effects were taken away from me, including passport and ticket. My Mom and sister who were traveling with me insisted on being in the room.

At the end no explanation.....no apology.
