A couple of times in the last two months, TSA decided to make EVERYONE trying to go through security go downstairs to that diamond area, but they didn't tell anybody where it was. The small signs are easy to miss, and the Information staff at the desk at the bottom of the escalators had to direct people to it. The diamond area wasn't set up to handle the masses. After finally getting through it, you had to go back upstairs to get to the gates. Ugh.
