0650 EWR C3 - 20+ people in line. Clueless would be a compliment. TSA trying desperately to get everyone to understand the rules and process. No one listening. Belts off. Shoes off. Laptops out. Frustrating for us non-kettle and equally frustrating for the TSOs who were honestly trying to expedite things and help. There were actually people on the precheck line with the precheck logo on their BPs who were unaware of why they were sent to the. IMHO oblivious despite help = back of the other line! please...
