I totally forgot I had an almost empty botle of water in my carry on bag. TSA found it (i am in PIT now) and pulled it out. As I wanted the bottle to refill I asked if I could drink the few remining ounces in the bottle (I had passed xray at this point. He told me NO, I had to go back through the xray if I wanted to drink it becuase it was a banned substance. That sounds really strange that I could not drink, in front of him, the remainder of a bottle of water......
