Soooooo... Went through security today and noticed I had a bottle of water in my computer bag. I looked around for a garbage can and there were none in evidence near the aluminum tables by the X-ray machines. I took the water bottle and placed it at the far corner of the table and proceeded to put my "stuff" into the plastic trays and go through security. When I got to the other side of the X-ray machine one TSA staffer came up to me and said, "You know these plastic trays are free." I looked at her and said, "Excuse me? They're free?". I had placed two laptops in one bin, side by side and she pointed at the bin. "We need to see both computers. You should put them in two bins." Lightbulb #1 went off - "diver90 just STFU and let it pass." Then TSA staffer #2 piped up, "Sir is that your water bottle?" "Yes it is", I answered. "Well you shouldn't leave it over there. You should go find a trash can and throw it out before you go through security.I should make you go back through and dispose of it." Lightbulb #2 - STFU X2 plus my best vacant stare. Hey, I know everyone is different but really?
