Dollar General review: Employee treatment

I was a customer and I have witnessed very bad treatment there was a very nice boy with a mix of blue and a lightish pink hair when he checked me out and I had to apologize to him for how he was treated there the manager was yelling at him for not finishing his stuff when there was too many customers to do so. The managers name I think is Abbey I seen her name tag. And he was trying his best to finish his job
