From MSNBC:
Don’t be surprised or alarmed if the next time you go through the security checkpoint at the airport you find TSA staff handing out smiles and warm greetings instead of barked orders, mean looks and stern commands. There may even be some TSA-approved hugging and high-fiving going on back there behind the X-ray machines.

It sounds farfetched, I know. Especially if you’re one of the many travelers who regularly ends up feeling demeaned and harassed at airport checkpoints and believes that the TSA only hires sticky-fingered miscreants who are missing the genes for courtesy and respect.
