Sounds like another one of our fine, upstanding TSOs was hiking up Camelback that weekend and forgot to buy a water bottle.

Here's a fun situation I've only seen happen once: TSOs doing a gate check confiscating water bottles. The guy sitting next to me on the flight had been stopped for a search before boarding, and when he got on the plane, he was fuming about his water bottle, that he had just filled up at the fountain after going through security with it empty, being confiscated. Apparently, it contained enough liquid to be a threat to the aircraft (what?!). Anyone else ever seen that happen?
