Bad service and lack of focus

Please advise your cashiers to focus when assisting customers I went for bread at boxer jeppe street and decided to take a swiss roll but the cashier only rang the swiss roll and plastic and I found when I got to the security and I had to leave the actual item I went for as morning rush I had to go to work I could not go back to pay for the bread had to leave it and it is such an inconvenience as now I have to go elsewhere to buy bread during work which is what I did not want to do
