“It doesn’t stink every day. But yesterday the smell was unbearable,” says owner Wieger Janssens of Restro TOF. What does it smell like then? “A bit of a poo smell, a sick sewer smell. Hard to explain really.” But it can be read from his face that the odor that is roaming around at that time actually belongs a few kilometers away at the sewage treatment plant. And not on the Markt, the catering square of the Drenthe capital.
