Dollar General complaint: Hateful Management

On 111522 I stopped in the dollar general to see what they had left for halloween sale. I had placed 6 items in my cart and noticed a few items that were to be pulled after their 90% off sale had ended. I placed those 3 items in my cart as well. I made my way up to the register and the cashier rang up my first item and it was a penny. She got mad immediately and told me that she had to pull those off the shelf. I said yes ma’am, they were to be pulled by Tuesday morning. She then said that she couldn’t sell them to me. I responded that she needed to read the DG penny policy and see that she was indeed suppose to sell them to me. She responded the policy had changed and I quickly said no ma’am it has not. She threw my grandsons sippy cup into the bag cracking it as I noticed later on. I got my items and left to go pick up my niece. I asked her if she wanted to go and see the leftover halloween stuff. We returned to the store and the same cashier followed us around as if we were criminals. She rudely said that she had discarded all of the penny items and stomped off. And I responded that she must have missed the 2 that I was holding. She turned around in front of other customers and demanded that I leave the store. I told her she would be reported and she said go ahead. I left the store and she asked my niece if she was with me. Yes my niece said and so she was then told to leave as well. This was at store 20706 in Port St Joe FL. The cashier key holder is named Susan. I shop my 3 local dollar general stores daily, I work hard for my money that I spend in these stores, and to be treated like a criminal cause she didn’t do her job is just sad.
