> for a small, minor thing like sloping the floor properly, it's a small mistake that won't really cost. I've actually met such a guy 20+ years ago, who didn't know slopes were a thing. He is from rural areas with extreme poverty, never had a shower room in his life really, came to cities for labor work regardless. I explained the idea of slopes to him, so he gladly spent the next few hours removed the tiles and made improvements. The new tiles are cut & adjusted like really ugly, but better than no slopes. I guess it's his first slope.
