That's right. The TSA would not let me fly with a container of sugar and ground almonds. Why? Because it's a paste, of course.
Here's my favorite part. The man told me that I had three options: I could have him escort me to someplace where I could mail it and then back through security, I could put it in my carry-on bag and have him escort me to the ticket counter to have them check my bag, or I could have him just toss it.
I'm not going to mail it. The shipping alone would likely cost more than it would to just stop by the supermarket on the way home from the airport and pick up a new tube. I also don't check bags. In my experience, there are only two types of luggage: carry-on and lost. This seems to be particularly true with Skywest, which is who I was flying with that day. Why Delta seems more interested in letting somebody else handle their flights for them is beyond me.
To me, it seemed perfectly logical to tell the man to just chuck it. But since he works for the TSA, logic works differently for him. He asked me three times if I was sure that I wanted to do that. Each time I told him yes. The last time I looked directly into his eyes when I told him that. I don't know why that works, but it does. He let me go on my merry way.
