The TSA is run by a bunch of rude, disrespectful teenagers and young adults. Their job is to move people through security and make sure they don't have any contraband. Occasionally they will pull people aside for a more thorough inspection. They despise having to pat down ticklish passengers, and have been known to tease and publicly humiliate anyone they find to be ticklish and keep them longer than they would otherwise, making them possibly miss their flight. You better do everything they say.
