Now that the TSA is expanding PreCheck to so many airports and allowing more pax to use it, why the heck haven't they tried to educate the newbies? Or even set them straight while in the line? For the past few weeks, both leaving my home town and also where I work, I have been stuck behind "joe pax" who, while in the PreCheck line, still thought he had to follow the non-PreCheck procedures. Shoes and belts start to come off. Laptops come out, etc. I suppose it's no big deal except when I'm expecting to breeze right through, which is every time. This morning, at the airport in the city I work it got even more interesting; The 2 pax in front of me weren't PreCheck. Usually there is an TSA guy at the entrance to the lines, reminding the pax of the 2 different lines, but not this morning. So I had to wait for both of them to be redirected, after they had their ID and BP checked. When the TSA lady heard the 3 beeps from my BP, she said something like "Oh, you're PreCheck" and smirked. I replied that I was and that the 2 prior to me weren't. She said "Oh, that's OK" and I replied "Not if you're standing in line behind them." Sorry for the rant, but I have TSA issues wherever I go and if they're going to increase the workloads in the TSA PreCheck lanes, they should educate all involved. Whats the expression? If you polish a turd, its still a turd? Something like that.
