Dollar General

I went in the dollar general store on march 4, 2014 alittle after 10am. I purchased a box of motrin which was 6 dollars. I paid and left. I was carrying the motrin in my hand. The parking lot was a sheet of ice as well. I was walking and a cashier came out and said mam you need to come back, you didnt pay for that. It caught me of guard and I said well I checked out. So I go back in and I said well she checked me out and I have a receipt. She said oh she checked you out I said yes. She said I didn't, I could only see you at the register and she said something about something beeping. She didn't even want to see my receipt, so I slammed my purse down and got the receipt out. I said I don't shoplift! I don't even think she looked at the receipt. I told her that was embarassing in front of people. I did let her have it I told her that I was calling the manager and the dollar general corporation and she laughed. Turns out the manager nicole as in the store. I know she heard me screaming at the cashier (Tabby). I have called they are supposed to call me back. I also made a complaint to th better business bureau.
