"How much do you want? Five catties of each?" The sales assistant's voice unconsciously became higher, and her tone was full of surprise. "One catty costs ten contribution points, so ten catties will cost you 100 contribution points. Do you really want that much?"
Du Yue nodded. "Yes, I want five catties of each." She took out her card from her pocket.
The salesperson saw that she was serious and did not seem to be joking. She turned around and weighed five catties of potatoes and sweet potatoes each. "Did you bring a bag? We charge a fee for the cloth bags here. Each one costs one contribution point."
Du Yue was stunned. The cloth bags were really expensive. She reached into the pocket at the bottom of her clothes and took out a folded square bag. "I brought it." The bag had been in her interspace all this time. She took it out when she put her hand into her pocket.
