I met in comments on the Internet:

Commander of part. The Colonel!! He sent KamAZ to the other end of the city to purchase two (!) cement bags, because there a cement bag is 50 rubles cheaper than here. The fact that solariums on this car run required the equivalent of seven bags of cement he did not take into account. Fighters have taken into account! Solarium was sold, bought here two bags of cement, the rest was drunk...This is the "savings".
