The empty fuel bottle confiscation is an example of why I keep my stove in my carry-on. At least then I have a chance to discuss with a TSO why it is not a WEI.

This past trip the TSO did a bag check of a scout's carry-on and pulled out his stove. I explained what it was and how it was not prohibited. Eventually she was satisfied. And on that same leg I did receive a love note from the TSA in my checked bag.
