You have been asked to develop a system for a local Thai food takeaway shop Curry Yum. The system should allow customers to order their Thai curries over the internet and collect them (and pay) at the shop. Customers do not register with the system but they do need to supply a contact phone number. A Curry has a price derived from its size, type (red, green, or yellow) and protein. A Curry has only one protein (chicken, beef, pork, tofu or prawn). Each type of protein has a different price. Customers have Orders and each Order is for one Customer. An Order consists of a number Items, and has a collection time. An Item is a Curry, Rice or a Drink. To place an order the customer must supply a contact phone number and name. When the order is submitted the customer receives a confirmation message along with the final cost of the order and a collection time. The system calculates the collection time based on the number of orders currently being processed and the average time to fill an order
