Have you ever been able to sense an attitude about a person even when they don’t say anything. Body language and facial expressions say a lot. Not saying this is what happened, but I’m sure they have seen quite a bit of it. Just keep in mind, they are doing their job. If there is an issue with the person that is one thing. But, if you don’t like how they do things - then that is a complaint for the higher ups, not the grunts.
I didn't "complain" to anyone, much less the "grunt" who groped me. I wrote a column about it. Further, there is NO ONE who is happy about going through a TSA checkpoint. Not smiling or being happy about it doesn't equate to "terrorist threat." If that's "their job," then they're crummy at it.
