Family Dollar review: manager

At 8:00 pm on New Years Eve 2018. I went to the counter to buy my stuff i explained to the cashier that my stuff was on Clearance age told me that they wasn't . I knew that she was new to the store bc i been going to this store over 3yrs and i never seen her before. She was very rude i asked to speak to the Nigerian guy who was the manager she said she was the manager. Where is it the customer is always right. I told het age must be new age said no im not. She was arguing with me so much she forgot to ring up all my stuff so she had to cancel out and start over. She was very rude and her customer service is bad she shouldn't be a manager she need to be in stocking. Or fired. As long as she is in the store i will not be going back in there.
