This guy did the job he was trained to do. Period. I’ve had the very same search done on me. Massively humiliating, but this individual doing the searching was trained to do it that way.
I always swish up with my gay voice and say “Now be thorough because I have been known to be naughty. And it’s OK to talk dirty to me while you do it”.
The kid wasn’t wearing clothing that could conceal much. A very cursory pat down would have been enough. The big question is why this kid. He falls within the age group pervs tend to enjoy the most.
