Weird people

Recently went with a friend to Peter for work. We arrived a little before the appointed time, so we strolled around all sorts of cultural places, galleries and concerts. Of course, all movements in the city were carried out using the subway.

Railway carriage. Quite a lot of people. A miracle sits on the spot for disabled people and pregnant women, which is represented in the picture, sharpening a knife. A large carving knife sharpens the usual red brick, while emitting corresponding squeaky-clanging sounds. People laugh, whisper, but they are afraid of asking about something.

Soon stop, the train slows down. The young man lays out the bags from under the laptop ASUS on his knees, opens the main pocket and puts a brick there, and puts a knife in the side pocket. He gets up, straightening the headset on his right ear, and goes towards the door. It is time for us to go too, and I, facing the door, feel its approach. He rises right behind me and as soon as the doors open he says: "The four hundred and fifteenth is in place, ready to work."

So, dear habrareyudi, I would like to know if this is normal? Maybe for some of you this is an ordinary phenomenon, I just did not notice?
