Dollar General

It was my the first time going to a Dollar General. I went with my sisters, there was only one cashier on a Saturday night. There was four of us on line, and another cashier when out when I asked if she was going to open another register she said we had to wait very rude. So of course we got upset for being spoken to like that. I told her there was no need for her to be rude, and she said just for us being impatient we now had to wait even longer and went into an office. I have never been treated like that anywhere. It was crazy! She said because of people like us was why Thanksgiving day was going to be her last day, she was going to BJs. All I can say is it was the worst experience ever! I understand its just a dollar store but some people should not be in customer service. We still waited the 30minutes to pay for our items.
