People are skeptical of rules to punish restaurants for wasting food as Zhuhai and Beijing released regulations this week.

The two cities followed Xining in Qinghai province and Linyi in Shandong province in their move to fight extravagance.

According to a regulation released on Wednesday by the authorities in Zhuhai, a city in Guangdong province, a restaurant will be fined 2,000 yuan ($326) to 10,000 yuan if leftovers are found on tables.
