Depends on which town. My little town where I get the mail the only thing there is the post office. And the counter is only open from 8:00 to 10:00. Ranchers stop in to pick up their mail driving quads, side by sides, tractors, feed trucks, pickups pulling stock trailers, and I would be certain people have stopped to pick up their mail while horseback. I will guarantee you none of these people clean up. Wife pointed out one person showed up at our little church in hip boots one time during irrigation season.
In a county where the cattle out number the people by at least 5 to 1 you will see ranchers and cowboys in town pretty much anytime you go to town. Some are in their work cloths, some get cleaned up. My guess is that it depends on what their mission is at that time. But the same can be said for the town people. Some are always cleaned up and some are never cleaned up.
