Family Dollar review: bad management

On 1/24 at 12pm the manager was being extremely rude to both the costumers along with myself along the bread delivery lady.
When I was in the check out I saw that an elderly lady was asking for assistance from the manager on something. Rather than providing assistance, he spoke harshly to her saying "it's right there just use your eyes". Then when the bread delivery lady asked him about where he wanted the extra bread and said "put it on the top shelf where the stupid people will see it."
I stepped out of the line and asked him to stop being so rude to the customers and workers. Then he turned around and lashed out on me and threatened to punch me in the face and take my purchased groceries away. He not only threatened physical harm but theft also all the while cussing me out in front of other costumers.
I have been coming to this Family Dollar for five years and never have I experienced this negative conduct. For myself and many other costumers this is the closest grocery store because most of us either walk or are disabled.
