Rudest staff ever! I was trying to purchase a walmart gift card with cash. Which ive done many times in self check out. They said i had to go to money services. Weird i thought but there wasnt a line so i didnt mind. I get up there the money services lady Carla says she will not sell me a walmart gift card and let me pay with cash becuase I was commiting fraud. Excuse me? Paying cash for a Walmart gift card is not fraud, unless the money was counterfit, mine was not though. I will be escalating your accusations to coorporate.
