T5's security theater is the worse.
My solution is to simply hide my personal liquids bag under my jacket onto the tray and if the guard with no customer service skills and no common sense asks if I have any liquids, I simply say no. The X-ray operator gets a clear view of my liquids, which is the main goal of the whole procedure and its only truly security-related task, and everyone is happy, including the guard who didn't have to intervene/argue with me about the shape/size of my sturdy clear plastic bag.
Oh, the theatrics of the whole thing! But why do they have to be so shockingly rude at T5 (and pretty much only there in my experience?)
