Mystery Man

So there is this man that comes and sits in front of the lobby everyday. He leisurely smokes a cigarette, takes his shoes off, oddly enough, and sometimes reads the paper, sometimes works on a laptop. He's always very nicely dressed and looks harmless, but he doesn't work here, and he never comes inside. I have no idea why he comes here, but he looks rather happy and peaceful, and its not like he's hurting anyone.

But why does he come here? It's not like we have a view, and there are plenty of other nice benches and stuff around all the buildings around us.
