BarBoss: Did you see in the shops powerful electric calls of the time of the Crimean war for security alarm? They are also called "chips", for the resemblance to the original? 20 years ago, my colleague, sleeping at work for the hundred-hundredth time, actually connected these breasts to the electromechanical alarm. For some time, together with him, all five floors and two adjacent entrances were put up for work.
