A six-year-old British girl, Mollie Price, is opening up her third candy store. She is said to be one of Britain’s youngest bosses. Her stores are called “Mollie’s.” She sells both British and American candy. The girl would like to open more candy stores. “It might sound crazy, but believe me,” Mollie says.
“It was Mollie’s idea to open up the shop. It is Mollie who runs the candy stores,” her mother Becky, her “business partner” says.
Her mother says all the stores are put together and stocked(进货)by Mollie. Mollie works in one of the stores every Saturday, then gets up early Sunday to go to the company’s product supplier(供应商). She asks her friends to test the sweets to decide which ones are good. She’s good at smart marketing. For example, if the weather is really cold, she sells the Mr Whippy ice cream cheaper than when it’s hot outside.
“Children have the best ideas. I tell my mum what I think and she always says I have good ideas. It’s just because I know what other children like,” Mollie says.
【小题1】What’s Mollie’s plan for the future?
