Maybe 'cause you weren't wearing a burqa?
I had this happen to me (The full Monte, that is.) a couple of weeks ago. The guy told me I had to empty my pockets of what was left in them and hold them in my outstretched hands as I stood spread eagle and he groped inside my clothing. At the end he took my money and my credit cards which I was holding in my left hand, and looked in between the credit cards. Of course I was flying back to my home airport (for the last 39 years) and they have records that I do this all the time, and can also know from my ID that I have lived at the same address near this airport for the past 28 years. But I wasn't wearing a burqa either.
That sounds identical to my story.
He seemed VERY interested in my wallet.
What seemed also strange is he looked me in the eye and asked “You got a problem?”
