People try to touch my things all the time and I am quick to sharply tell them to stop. I try not to let my things make it through the x-ray before I do but sometimes morons who can't figure out to take their keys out of their pockets have to walk through over and over removing one piece of metal at a time. What's so irritating about people helping with your stuff is that you can't tell if they're trying to steal it or not. I never touch other people's things and they need to keep their hands off mine. This includes not only people in the security line but also overeager valets. Don't pick up my suitcase, my security bin, or any other object without my permission. Period.
