I'm just back from a quick EWR-LAS trip with just a small carry on bag. I dutifully packed my 'liquids' in the required clear zip lock bag, and when I arrived at the security checkpoint in both LAS & EWR, I took the plastic bag out of my carry on and placed it in the available grey box along with my coat, shoes etc. Looking around, I noticed I was the only one on a very long line of people going thru security to do this??? While they kept making announcements of the necessity for placing the small containers of liquids into a plastic bag, I didn't see anyone else taking this bag out of their belongings. Was I supposed to just leave it in my packed bag--as the others clearly must have? My bag, nor others before & after me, were stopped and I had no problem getting thru security, but was wondering about this issue.
