TSA Checkpoint D

The TSA opens the security gates about an hour before the first flight of the day starts to board and today, they started their thing at 4:25 AM. There *is* a PreCheck line where you get to bypass the radiation machine if the TSA deems you to be worthy. Otherwise, there is a regular economy line and a special line for preferred/​elite passengers.
For me, I was through in a minute or two thanks to PreCheck. Without that, it was looking like as much as 30 minutes. Plan ahead!
Note that each of the terminals at this airport are separate security zones so you can’t go from the D gates to another terminal without exiting, taking a long walk, and then being re-​screened by the TSA.

Was just expecting one TSA for the entire airport, but someone has them divided by Checkpoints (maybe there’s a reason/​difference for that). This was the Checkpoint I had to get through and it is the worst checkpoint I’ve ever been through. TSA needs to remember that requests are different at different airports and flyers aren’t always going to know which of them want which things off and on or separated, it has changed multiple times. That being said I’ve been to TSA Checkpoints that have efficient and courteous staff, but these folks were crazy rude.
They were yelling at people straight off the bat, without even requesting in a normal tone beforehand.
They also allowed a total «D» who was in the elite/​express line already to cut in front of the non-​elite line (right after we got through). He had already blown by 100+ people because of his express pass, but the one elite/​express man in the wheelchair in front of him was too slow and he pushed his way up to the normal line saying «I get to get through, I shouldn’t have to wait like this». It’s one thing if he was trying to make a flight, but I saw him after and he was nowhere hear missing his flight. He also knocked my friend hard on the head with his luggage trying to put his stuff up in front of ours on the belt shoving our stuff back even though we were in front of him in line. TSA again did nothing. Seriously people, organize things better and keep the jerks in line.
