I was once a young Marxist, only after universe. I decided to work on one building. And it must be said that the workers there were some former Zeka, and local calliers. Well, they poured the foundation out of concrete, but here is the trouble - too much was enough, higher than needed. Well, and I have the first task from the boss - measure everything and measure, how much extra stuff is poured and placed on them, how much to borrow, they will make breaks for the night. Well, I measured everything and placed on the area of the tablets - there 200, there 100 to remove. Well, as they taught, everything is certain - in millimeters.
I come in the morning - the men are all barely alive, in the head in the concrete places. It turns out that they were used to measuring in centimeters... You would see their faces when I told them to roll back O_o.
