I bet there's more to this story than the OP is letting on. I can see the yellow line in the picture. You only need to see 1 yellow to know where to park. It'd be even easier to see the yellow line in person. From my experience with renting, there are a lot of really terrible & dumb tenants who don't even try to follow basic rules or warnings.
