A few months ago, I had a run in with the TSA at DFW that ended with the screener telling me, "I remember you from last week. You don't deserve PreCheck and shouldn't have it." The funny part was, I hadn't actually done anything wrong (nor had I been through DFW the week before), but I did do something that set her off.

My PreCheck is by virtue of Global Entry. Can/will TSA revoke the PreCheck part for something that was not remotely against any kind of rules? Has anyone run into a screener with an apparent personal vendetta against them? Does such a screener have the authority to mess with a traveler's trusted traveler program? Can this affect my Global Entry status?
