Agree to disagree. Everyone has their own tolerance for what is acceptable to wait, and at this point I've come to terms with security checkpoints being just one place where a wait is currently necessary. Also while I do have a Key, I'm not local as I don't just pop down every day or even every weekend. I go a could times a year and just accept what has occurred, as I said before its something I've even experienced at other venues just as NFL games.
Have you used the new scanners though? They are looking for larger metal objects (knives, guns, etc) and thats what gets flagged. Stuff that poses a safety risk. Nobody is rifling through your retainer case or wallet and whatever is in there is almost certainly small enough to not set the scanner off.
What exactly do you think someone is gonna have in their retainer case that warrants making thousands of people wait an extra 30 minutes?
