The Hard Candy Counterattack

Zane Fang's son went to the supermarket, only to be given candy as change by proprietress Chloe Sun. Zane discovered Chloe Sun had long infringed on residents' rights under the pretext of "having no change". Faced with this, Zane chose to collect evidence legally and defend his rights rationally. He gathered proof of Chloe Sun using candy as change, and used the rules the shop owner had personally acknowledged to remind everyone to value consumer rights.
