Security guards ask the buyers who go out of supermarkets No. 1 to present the sales slip. They check them and put the stamp ‘security check’ on them, Info-Prim Neo reports. Asked to explain the necessity of such a new procedure, Olga Petrenco, hall chief at one of the mentioned supermarkets, said the guards verify if the goods from the bag match those indicated in the receipts. Olga Petrenco specified the method has been employed for several days only in supermarkets No. 1 and there were recorded no complaints from buyers.
