I don’t think it happens much to her.
I got my hand swabbed prior to a recent flight by TSA. A female TSA employee yelled “Males...” after she informed three of us that a random inspection was underway and we were those chosen. The three of us were told to stand against a wall and she shrieked “males” a second time to notify a male TSA employee had to conduct the test. Isn’t that precious. And at no point were we told the purpose of the test. All this to fly. I would have preferred being called sweetie.
