I'm sitting at a hi tech conference with my laptop connected to one of the scarce outlets. There are hundreds of people and precious few electrical outlets. We're all ADD. We need to work while listening to a bland panel of hi tech marketers.
Most people with laptops walk around looking for a plug. This guy with a laptop walks toward 2 of us that own our plugs. What is he doing? You can't kick us off.
He pulls out a 3 to 1 extension and asks if he can hook in. Of course, we say yes.
What a clever way to make friends.
