With no sign of workers or even an owner, customers pick the products and pay by themselves in a distinctive coffee shop in Hanoi. Customers opt to choose their drinks, print invoice, pay cash, even clean the table after finishing. The first ever self-help café in Hanoi sells nama chocolate, ice cream and food. It counts on shoppers’ honesty and freedom to earn a profit. After two years of operation, only six cases of shoplifting have been discovered.-VNA
