Dollar General review: cashier

I entered the store, visible employee, said good morning, amended to good afternoon. I was accompanied by my husband who is white. I am a black female. I had no purse or coat as its summer in Texas. sweats so no pockets. The cashier followed me to the aisle I was in, busily doing nothing, just looking at the shelves. I dismissed it as coincidence but as she lingered I moved to the next aisle. Again I was followed to this aisle, again she's looking at the shelves, fixing nothing. Her name is August. She never moved to any other aisle even though the store at the time had other shoppers including my husband. I was and am very disturbed about the incident and will also file a complaint with the corporate office.
