Mt. Pleasant Dollar General Store Return Policy & rude manager

Once again, after being assured by DG that they were going to get rid of their rude manager I started shopping there again. Well, guess who had to take back my return, the same ole WITCH. This time I did not allow her to give me cash back as she requested, so I could keep my receipt without a fight. Well, she had to call another store to find out how to apply to my credit card. Then would not give a copy of the credit receipt for my records. Was she trying to show her authority??? I am sick of this manager and they need to fire her as they assured me they were going to do after getting my receipt thrown at me the last time I had a return. Wake Up DG, I'm sure I am not the only one she is treating this way!!!!!!!!!!!!!!
