The dollar tree in Mount pleasant iowa is horrible. I will never step foot in another dollar tree store ever again. Based on the behavior of the manager there Samantha shumaker. When I was shopping there she was being verbally abusive to her staff. Yelling at them in the office so loudly I could hear it on the other side of the store. Repeatedly screaming that her employee was a liar until the point she was crying. It was appalling. Then as I was leaving I saw her outside smoking, and on her phone. While she left the girl on register with a huge line of customers and no one came to help. I can't believe they let people like that be managment.
