Complaint Review: Dollar General

I walk up to the store and struggled with a cart and went into the store and a short overweight woman said "There she is I have been waiting for her and she is using a cart because a ambulance driver was trying to take a picture of her the last time she was here. Then she gave a order to the another worker to stay at the front and said she was going back to watch the camera. I decided to stay and shop and then this same woman appeared in front of me and then I checked out and there was a man who I have spoken to in the past and this time I remain silent and as I left he went and said to someone "she did not say anything to me." Now I do not know why it was said or that a ambulance driver was trying to photograph me the last time I had shopped at this store. It creeped me out and that this store employee said it. How does a ambulance drivers have time to be stalking people to photograph them? Why is the Dollar General in store security system is being used for personal use? Furthermore I want to know beside shopping what am I doing? Doesn't Dollar General want customers?
