In my current shop and the shop in the plant where I used to design in we employed nothing but Guatemalans. Apparently in their country personal hygiene took a backseat to most everything else. They too ALWAYS disposed their toilet paper in the trash. It was customary for them because the plumbing in their country is atrocious. Flushing paper was sure to cause a backed up mess so they never did. In the trash it went. Then they come here and we compare their standards to ours and get offended something fierce. Shoot in the summertime a lot of them still prefer the woods.
It's just where they're from. They come here without any proper sanitary etiquette.
