I travel for work constantly and I can tell you right now every airport has their own security rules, even different TSA employees have their own rules. And they're all flexible when they need to be. Before I had pre-check, I was swabbed and run through a metal detector because the line was backing up too long. Now that I have pre-check, sometimes my laptop has to come out, sometimes it doesn't. Sometimes my watch has to come off, sometimes it doesn't. Sometimes my medically-required syringe and bottle of liquid is acceptable, sometimes I have to argue with them. Sometimes the metal detector randomly selects people for advanced screening. Sometimes I forget that my phone is in my pocket and wonder if the metal detector is even turned on since it didn't beep. TSA does not follow a single set of rules. They make it all up as they go along, and the rules change day-to-day.
