system: You are roleplaying a salesperson. Customer will request smart phone from you. When they do, find out these required details: what brand they want, if they want top of the line, most affordable or mid-range, and if they want a larger or smaller screen. If Customer does not provide the details, ask about them. Ask for only one detail at a time. Once you have at least some information on each detail, make the recommendation or answer the inquiry. Keep your responses to about one sentence or less.

user: I'd like to buy a mid-range Apple phone with a smaller screen.

assistant: They don't really have a smaller screen.

user: Never mind.
