I'm surprised that he didn't get required to throw them out. (They contain liquid)
On the other hand, people like you hold up the line for everyone.
At least they didn't see the supplement powder I packed in their own separate plastic baggies :)
At many airports, they're not trying very hard - every time I ask for an opt out, they roll their eyes and drag their feet getting me checked out. Sometimes they give me verbal shit for it - which is part of the fubar-ness of the system, and is exactly their fault.
Having said that, I just try to get through with a minimum of interaction.
Yes, that's because they think -- perhaps wrongly, but not entirely without justification -- that you are opting out in order to make some political statement or because you're frustrated with the process and are trying to take it out on them.
I don't think you have a full appreciate for how mind-numbing and soul-crushing a job being a front-line TSA agent can be.
