When can ShoppingHelper help? -Using Scenario

Mike is a young programmer working for CodeFarmer Inc. He just graduated from school and started his professional life. As the workload in CodeFarmer Inc. is very heavy every day, he barely has time to go to Walmart and gets what he needs. Therefore, he usually does online shopping and needs something to help him remember what he needs. Whenever he finds something is running out, he can simply tell ShoppingHelper "I need [something]". Then, he will get some refined recommendations from ShoppingHelper on what he needs. Once he selects one, he can tell ShoppingHelper to "add [it]" to the shopping list. When he does online shopping or in the market, he can simply ask ShoppingHelper to "display all items" on the shopping list and finish shopping in a second.
