Dollar General review: Poor customer service provided by store manager (Renee).

On 7-1-20 I experienced HORRIBLE customer service at the Dollar General on Phillips Ave here in Greensboro Nc. When I got to the check out there was nobody at register 1 or 2. The light was on at #1 so I placed a cart full of items on the counter. Renee (store manager was on her shirt) comes from around the corner almost three mins later and says "I'm at this register " as she was walking up to register #2. I asked her if she wanted me to moved ALL my things to #2 and she just gave me a blank stare and started cracking her knuckles on her hands. So I begin to move all my things and I say to her "you realize that this light isn't on this register and it is on the other one right" and she completely ignores me. So I ask her if she heard what I said about the light and she rolls her eyes and said "I heard you". I paid for my things and left. Realized I forgot paper towels and went back in the store. When I enter the store she is talking about the fact that I said something about the light to another employee. The other employee then explained to the "store manager " that she should have given me an explanation as to why the situation took place" the other employee then apologized for the store manager. After speaking with my wife about the situation we will no longer be shopping at this or any other Dollar General. If Renee (or the person who said their name was Renee wearing a store manager shirt) remains an employee Dollar General will lose customers daily! She either needs to be retrained, demoted, or fired.
