A restaurant in China has apologised after encouraging customers to weigh themselves before eating their food.
The beef restaurant in the city of Changsha placed two large scales at its entrance, after they introduced a policy following a national campaign against food waste.
As customers entered, they asked them to enter their measurements in an app.
The app would then suggest menu items according to their measurements and weight.
Signs reading "be thrifty and diligent, promote empty plates" and "operation empty plate" were pinned up, according to the BBC.
