Why doesnt big ma take Cassie advice to move the farm wagon forward where customors will notice it?

Big Ma may not take Cassie's advice to move the farm wagon forward because she may have her own reasons for keeping it where it is. It could be a strategic decision based on foot traffic flow or other considerations that Big Ma deems important for the farm's success. Additionally, Big Ma may value tradition and prefer to maintain things as they have always been done.
