When making a purchase, the seller gave the change taking into account the price of the goods on the price tags. I hastily crumpled the stamped check and was about to throw it in the trash, but I asked to give it back. When leaving the store, I decided to check the receipt, and found out that the amount of the receipt is less than the amount I paid. The seller applied a discount on the purchase, but decided to give the change taking into account the prices on the shelves. Returning to the store a few minutes later, I turned to the seller, who, without wasting time figuring out the problem, politely and calmly gave the remaining amount of change, taking into account the discount. Taking into account the nature of the seller's actions, there is a high probability that the situation is systemic. For information to tourists and relocators. I give two stars, because according to the school grading system in Serbia, a two is a passing grade :))
