Walmart complaint: Check out personal

I went to Walmart this afternoon and did NOT have a good shopping experience. I was at self checkout… struggling to NOT let my anxiety get out of control…to anxiety mode. My card didn’t work,and I had to borrow money from my friend..who was in the next register. I DID NOT HIT THE CLEAR BUTTON.BUT IT CLEARED ANYWAYS. THE PERSON at self checkout was rude and argumentative with me. So I had to redo check out..my anxiety level was almost more I could stand with her condisending attitude. She made me feel like a price of crap. Insisting it was my fault. Well,my friend went through the same with this woman. The woman told my friend something didn’t go through and to rescan the item…I WATCHED MY FRIEND RUN HER YARN THROUGH.THE ASSOCIATE MADE US FEEL LIKE WE WERE BENEATH HER, BECAUSE WE’RE SENIORS…AND WE FELT SHE WASN’T LISTENING..SHE ONLY WANTED to hear what she wanted to hear..and we were liers and we were trying to steal..
