A few minutes later when we returned to our seats, I saw who the owner was. Fortunately it was someone I have worked with in the past, so I might not seem like a total loon when I asked him for can when he was finished with it.
At the next break I took a deep breath and did what I've actually become rather accustomed to doing... I asked if I could have his can when it was empty. I got the typical "This? Why?" look, but I explained about my collection and then he understood (or at least he said he understood). Either way, I had a new can.
He said his girlfriend had bought this Dasani apple flavored water. His review was not so good. He named a few other brands he'd rather have, which led to a short discussion on flavored water.
And THAT is what I got out of my leadership training. I call it a success.
