Irony at the cigarette machine

I love riding my new bike around. I thought that I knew Kaiserslautern reasonably well, but Stevens, my bike, helps me learn even more about the area as I venture forth into new frontiers.

During one new expedition, I saw this cigarette machine at the end of someone's driveway. The cigarette machines are similar to the roadside candy machines: they're often attached to either an office building or a house house. I have to say that this is the first one that I've seen attached to a garage.

I thought it was funny that the sign right above it says that smoking is forbidden. Um, why sell cigarettes then?
