I've been shopping at this location over 10 years NEVER EVER have any bad customer service until today! I happen not read self checkout not excepted couponsROBINhelping,I asked for manager but she seem not to listening i was trying to let she know this is not gonna be the first and last time that she is going to experience about this mistake! Call the manager and we all can go home happy! She is still insist not to do so, I said..I don't wanted to argue with you, just cancelled. While miss southern accent emptying my groceries bags. I was saying that she is lucky that my husband isn't her! So ROBIN has to said with unwell manor" Why, is he gonna threaten me"? That's the most unprofessional I have never receive in Walmart. I don't wanted to said is just because I'm black or yet is because I'm Asian but somehow I'm looks black to her! She is making sure of that I really got her name while I'm asked security for manager. It's law suit out there! I'm not the one who is going to do that but as long as Walmart hiring staff like ROBIN, it will be! I would give Walmart 5+stars but staff name ROBIN just ruined.
