TSA Screwballs

I am sitting with my shoes off in the Baltimore Airport, right outside the TSA checkpoint. The TSA just took my toothpaste because it was in a tube that had a net weight of 4.6 ounces, or 130.4 grams. The online TSA regulations prohibit "3.4 ounce (100ml) bottle or more (by volume)". Note the emphasis on volume. When I tried to explain the difference between weight and volume, they looked at me and said, "This is 4.6 ounces. We prohibit anything more than 3.4 ounces." I showed her that the container itself had to be less than three fluid ounces, because three fluid ounces is a bit more than six cubic inches, and and the toothpaste tube was less than an inch in diameter and only about four inches long. She then said, "Would you like to talk to my supervisor?"

 

"Yes, I said." He came over and said the exact same thing. I then gave up because I realized I was talking to a bunch of college drop-out idiots.
