I was at a department store almost 2 weeks ago looking around for nail stuff. I got some but placed them back on the aisle cause I didn't want them. As I was going around the store, security approached me and asked me if I was looking at the nail section and he was holding the things I returned. I said yes but I put them back cause I didn't want to buy them. He then told me to leave the store and not come back. If I will, I will be prosecuted. As I was out, he ran after me and asked me if I had taken something that I didn't pay for. I showed him all the contents of my bag to prove to him that I didn't. He then told me to not return to the store. The cops were not called and none of my information was taken. What should I do? I have shoplifted before but wasn't caught. Thanks.
