Worst experience i've had with a cashier

This is the second time i'm helped by a cashier with bad attitude at that bonjour shop .. today i'm buying food with my card and this cashier tells me she don't take cards i must go to the 2nd one So i went to siphokazi then she told me whatever happened on that matchine is gonna happen to her as well (bad attitude) so i asked her to try cos i did'nt have cash then she said \if i try and it declines who gonna pay"(bad attitude 2) i told her i told her i'll withdraw cash if it declines "
