Why does Microsoft go to the cafes I go to and know the people I know?

I was just installing some software for this new LifeCam HD when I saw this picture. That looks familiar, I thought. In fact it’s more than familiar, I was just there. And I’ve met that girl (very attractive in real life). But why in the world is Microsoft taking candid photos at Bauhaus?

Do you guys ever find yourselves or people you know in stock or product pictures? I wonder how often that happens without a person’s knowledge. I suppose with all the shots Microsoft needs to have of people using their stuff and looking normal, just about everyone in Seattle is going to be a poster child for them at one point or another.
