I often wear a camoflauge shirt to Walgreens or Lowes during the winter. I don't wear the trousers because it looks silly, and I don't want to get the scent on my hunting clothes. But maybe they are small game hunters.
Did their choice of apparel do you any harm?
Or they are coming from or going to work. A lot of people who work with their hands use a fixed-blade knife.
