A Chinese businessman has begun a crusade to remedy his country's "moral crisis" by opening a restaurant where customers only pay if they want to.
Liu Pengfei, a 51-year-old from Fuzhou in southeast China, opened his "Good One" buffet in August in what he said was an attempt to rescue a long-lost sense of trust in Chinese society.
The restaurant's menu, a blend of Chinese and international cuisine, is nothing remarkable.
What is unique is Liu's business model. For customers can pay as much or as little as they want - and can choose not to pay at all.
Liu, a Christian, said his idea was to build trust by offering diners the choice of doing the right thing - paying - or taking the dishonest path of leaving without settling the bill.
