So, what do you do when you're on a business lunch with your Regional Vice President of Operations and you notice he is drinking from a can you don't have in your collection?
You ask, "Can I have that can when you're done with it?" That's what I did earlier today.
I am used to the funny looks. I am used to explaining that I have a can collection. I am used to the awkward silence after asking someone for their trash. But it's that awkwardness that helps them think of me the next time they have a can in their hands. I have had the conversation about my collection with several people that have come back to me at a later time with another can and asked if I have that one yet. I think it makes people feel good when they feel like they've contributed.
So if you're ever in public and someone comes up and asks if they can "throw that can away for you when you're done," it just may be me you're talking to.
