If one inappropriate comment "destroys all of your work," then that work probably isn't very significant.

Don't get me wrong. I'm not saying that there aren't good screeners. Quite the contrary. In fact, I think that the good screeners should take pride in their work and spread good things about the TSA.

But at the same time it's important to realize that there are bad apples in the organization and bad experiences among the traveling public. Wishing it away won't do any good. Better to accept it and work to being the best you can be and encourage others to do the same. Ultimately the bad ones will (hopefully) be weeded out and the overall reputation of the TSA will improve over time.

In the mean time, don't take negative comments about the TSA personally. People are angry at the delays, inconveniences, and at the few rude and unprofessional screeners that they have dealt with. Chances are you are not personally responsible for their unhappiness so it's silly to take offense at their comments.
