Don't be afraid. According to your account, the total value of your theft is only 300 yuan. According to the relevant provisions of China's current laws, your theft value has not yet reached the criminal filing standard of 500-2000 yuan. So your behavior does not constitute a crime, but your behavior is obviously illegal. According to China's "Public Security Administration Punishment Law", it can be detained or fined. However, since you are a college student who has just entered the society, considering your present situation, you bought what you stole, and the supermarket has no loss. I don't think the supermarket will call the police. Even if the supermarket calls the police, the public security organ will impose a fine or even a maximum warning on you according to the actual situation. The supermarket will not spread videos about you, otherwise it will infringe on your reputation. I don't think it will be willing to take such a risk. But you should realize the illegality of your actions and take warning, and strive to be a good citizen who abides by the law. I hope you don't flinch because of a temporary slip, but you should put down your burden and cheer up. "Sister, you go forward boldly." Don't hesitate, don't hesitate, the future is bright and success is waiting for you. The above is long-winded, I hope it will inspire you. You can send me a message at any time and I will try my best to help you.
