Dollar General / customer service

On February 11, 2019 my 15 year old granddaughter enter your store at 234 Old Sardis Rd, Oxford, MS 38655. When she got to the check out the cashier never spoke to her and did not turn the bag holder around for her to get her bag. But she heard him speak loudly to the white lady behind her. I know she has to be telling the truth because I had just left the store 30 minutes prior. We love the Dollar General Stores because they are a convenience to our home. I do not like my grand kids feeling this way because we did not raise them to act like this. They are very respectable I would like for them to feel they are same no matter where they go. When I was in there I made him speak because I have learned to look over some people because they don't know better.
