Every rental is due three days after it is taken out, every rental has at least one item, an item comes back after it went out, and the late fee is exactly $1.50 for each day past the due date -- nothing when it is on time. The payment at the counter is $3.99 an item. Every film has one director, one studio and at least one genre; stock is bought from vendors on purchase orders that total their lines at the price of the format.", "domain": "media", "shape":
