I will NEVER buy ...

I will NEVER buy anything from here again.I accidently grabbed my visa instead of my debt card to pay, the women who rang me in lost it at me. She started screaming at me(while there were other customers in line)about how she was now going to have to pay $2.00 for my mistake.I offered to give her the $2.00 but she refused.I asked to speak with a manager and she said I didn’t want to do that because he would rip me apart more than she was. Who says something like that to a customer?
