When I was a student, I worked in radio. He received an unusual task for the green young man - to carry out a patch cord outside the building under the roof. Since it required permission for high-altitude work, which I did not have, I was sent to the office of the security technician for instruction.

The instruction turned out to be short: "Don't get there," the person in charge said and extended the journal to me for signature.

I followed the instructions, it really works.
