Dollar General review: employee screaming and cussing

I was shopping in this store and all I could hear was the blonde girl with glasses screaming and cussing at a ladie not to come back to her F-ing I understand if someone is not supposed to be on the property but there was a lot of people in the store and all of that I think was uncalled for I hate it because I've always enjoyed the people that work there. P.s. there was children in the store at the time of this incident!
