The cashier said that your friend can only exchange paye cards with qr because the Pos is broken. I barely set up a Qr, I saw that there is a contactless feature in the Pos mskinada he was processing! Moreover, he set up a paycell Qr instead of a paye card on the Pos machine, and we dealt with it. The last time a friend who knew came, paye qr was selected and the shopping was completed. It would be nice if you inform the cashiers about these issues. Both we and the cashiers do not get tired for nothing.
