Those pesky Denver TSA workers. I remember traveling there last fall from PHX. On the way out of DEN, I had to remove my liquids/gels from my carry-on that were stored like they were supposed to and place them in a seperate bin through the x-ray. Out of PHX, I did not have to do this.
I told the supervisor about it and that a little continuity would be nice. All he said was, "Well, this is how we do it."
