Walmart review: Customer service

On 11/11/22 Walmart in Richland Washington 99352, a cashier treated me badly just because I don’t know how to operate the debit/credit reader card and also I forget my PIN numbers. She kept shaking her head and kept saying “Ai yai yai!” What the F — -is that mean? I kept thinking to myself. Is she trying to say something is wrong with me? …Well, I felt embarrassed and humiliated. I didn’t want to start a fight with her then because there was a long line. It will be a long long time before I ever go back to that Walmart again. The cashier name was Carmen.
