What's wrong with an uncle who forgot to eat "crayfish" on the subway in Shanghai and scared the passengers?

An uncle in Shanghai forgot to eat crayfish on the subway, scaring the passengers. So what's wrong with this uncle eating crayfish on the subway?

First of all, according to a passenger on the subway, when she was about to go home from work, she sat next to her uncle as soon as she got up, and then she found that the uncle had begun to eat crayfish with relish. She began to be shocked. She was the first to stand up and stand opposite to observe for a while. The uncle had been immersed in eating crayfish for more than 1 minutes, but during the whole process, no one stopped the uncle from eating crayfish on the subway. The reason why this lady is so excited is mainly because Shanghai has just been unsealed, and the subway is a public * * * occasion, and the people are dense. The uncle eating crayfish on the subway may have an impact on the local epidemic. Although everyone needs to scan the code when entering and leaving the public * * * place, eating crayfish is always not a good thing in crowded places.

Secondly, the Shanghai Metro said that eating and drinking were forbidden in the train, which leaked the rules for rail transit passengers. However, it was not written into the management regulations, and it was only possible to criticize and educate from the moral aspect, and the passengers stopped it, so it was impossible to punish him legally for the time being. Therefore, this uncle could not punish him for eating on the subway, but only criticize and educate him from the moral aspect.

Thirdly, I believe many people are very helpless about this uncle's eating behavior on the subway. If we communicate with him, he may have a conflict with the passengers, thinking that others can eat on the subway, and why he can't. Therefore, from a moral point of view, this uncle eats on the subway, and it may be because other passengers in the carriage have the same behavior that he will follow suit.

Finally, there is obviously something wrong with this uncle eating on the subway for local epidemic prevention and control, because the subway belongs to a public place and a crowded place. If he eats on this occasion, it may bring inconvenience to others.
