Clockwork Apple: No Smoking

Everyday, as I walk to and from work on part of my commute, I pass through this office building with an underpass. Each time I do this, there are always 2 people there, James and Linda. They both work in the same office, but not the one with the overhang that I pass by and they hang out in front of. They just chat away every day and light up a couple of cigarettes. The building also has several large signs that say "No Smoking," but it's obviously never enforced. Two people smoking outside of a building might be something every commuter sees daily... nothing special. But James and Linda are there for both the morning and evening rush... like clockwork!
