An advisory from the TSA: "For those traveling by car this Thanksgiving week, be advised that convenience store clerks are NOT authorized to perform pat-down searches, even if they're wearing what appears to be an official blue TSA shirt. Also, bus travelers should NOT enter any bus-station rooms labeled with a handmade sign that says 'Git YoUre bOdy ScanNed HeaR.' The TSA thanks you for your cooperation."
