Create a sequence diagram for each of the following scenario descriptions for a video store system: A Video Store (AVS) runs a series of fairly standard video stores:

• Every customer must have a valid AVS customer card in order to rent a video. Customers rent videos for three days at a time. Every time a customer rents a video, the system must ensure that he or she does not have any overdue videos. If there are overdue videos, they must be returned and an overdue fee must be paid before the customer can rent more videos.

• If the customer has returned overdue videos, but has not paid the overdue fee, the fee must be paid before new videos can be rented. If the customer is a premier customer, the first two overdue fees can be waived, and the customer can rent the video.

• Every morning, the store manager prints a report that lists overdue videos; if a video is two or more days overdue, the manager calls the customer to remind him or her to return the video.
