Dollar General complaint: Rude and disrespectful

Was followed around store but not offered assistance. When I asked for price of product she said these are the same price as (and walked over to a different location ) these. She did this twice. The xmas display had no price of products and walking back forth to find price seemed time consuming and frustrating and should have just been priced on display. She was sarcastic and made me feel embarrassed and stupid. She stood behind me at self checkout which I have never used but offered no assistance and when I did She snapped at me like I was irritating her. I felt humiliated and embarrassed and started crying. When I completed my transaction and got to the exit She exclaimed laughing loudly have a nice day waving with exaggeration. I cried all the way home was upset the rest of the day. Why did she treat me so awful? She made me feel like a criminal who should be stalked and harassed. I have NEVER shoplifted in my life didn’t carry a purse or bag only stopped to get a bag of flour it was the most horrible experience in my life. I didn’t deserve to be put through that and I will never again shop there again it was just down the street from where I live but I will go somewhere else to avoid going thru the humiliation of being treated like I was by the employee. Everywhere I went she was right behind me and when I stopped she didn’t offer assistance but said she needed something behind me. Everywhere I went? I am NOT a thief don’t appreciate being treated as such nor do I appreciate being spoke to like I’m a idiot. Like I said, I didn’t carry anything but my wallet with money in it to BUY my items. Now if I went in carring a large bag it would maybe raise concern of shoplifting. I will NOT put up with being treated like a criminal either because I am NOT a criminal!!!!!!
