How to monitor and prevent theft in the school canteen? After contracting it, we found that it was losing money every day, and the employees complained that they could not take care of it! !

I am a student. Our school’s canteen does a very good job in preventing theft and it is not labor-intensive.

Ask a staff member to stand on a stool so that he can see the entire store, and then use a loudspeaker to warn over there. In fact, this does not occupy manpower. It only needs to send someone to stand during the peak period after school.

Slogans must be posted, such as warning signs such as "Calling parents for stealing".

It is necessary to install cameras to deter the masses.
