We have a security guard at work. Such a healthy man. He knows thousands of terms and generally all kinds of cool security chips. Well so here. Someone at work is trying to eat someone else’s food. It will get out of the refrigerator, eat, wash the plate and put it back. We put a camera in the kitchen. And now our cool security guard comes up with tasks:" Please help me find my kefir". This is so. He also studied in graduate school.
