Diamond Gasoline Station #11 in Monroeville, AL

I went to the store which is a 24hr, 7 day a week store and pumped gas at approx 212 am. Another person came to the store and went in and purchased something and left. When I finished pumping my gas, I attempted to go in the store with my children to buy a drink and the clerk locked the door and said it was closed. Let me remind you that it is 24 hrs. I'm not sure if she locked the door because I was African American because 10 minutes prior to that a Caucasian customer was allowed in. I'm pretty sure she is prejudice. I will never purchase anything or go here again when I visit Monroeville. Poor customer service and this business will never see any money from me again. I wish I could give 0 stars.
