A clause added to the draft regulation of Shanghai metro management forbids passengers from eating on trains. Before the clause was added to the draft, surveys and opinion polls showed that more than 80 percent respondents favored such a ban in certain sections, says an article on gmw.cn. Excerpts:

Though commuters may differ on forbidding people from eating on trains, there is no denying that such activities create a problem for sanitation workers.

Many people still spit on and litter the streets despite knowing well that they are unhealthy habits. Perhaps regulations are needed to force people to change their uncivil and unhealthy habits.

Therefore, the public should support the draft regulation of the Shanghai metro management forbidding passengers from eating on trains. People who don't have enough time in the morning to eat breakfast at home can have it on the platform before or after boarding a train.

If people can abide by civil rules there wouldn't be any need to impose regulations. After all, laws and regulations are needed to make people follow certain rules that are beneficiary to society as a whole.
