Can I still be charged if I was already stopped for shoplifting outside store but let go as I had nothing in my bag?

I accidentally had walked out of a store in shoes I was trying on because I was working in store as a vendor. I was approached in parking lot at my car by security and told he missed me at the door to do a bag check. I let him look in my bag and he saw nothing and was going to explain about the shoes but it didn't feel like a good idea and I was freaking out and just said or did nothing. He said nice shoes and I said yeah and he said something about vendors being like employees and after 10 minutes said his name and asked me mine. He said hope to see you in the store again. I said nothing. Then I said I was leaving had to go and left. I am a vendor that goes in this store every week but since this happened 3 weeks ago I have not been back to this store but have been to other stores in the chain I service. Should I go into the store where this happened? Or should I quit my job and stay away from store and hope I never hear anymore about it? I have never done this before, it was an accident. I have been a vendor for 15 years and have never taken anything from any store. But I don't want to lose my job. I also do not want to be formally charged or to go to court. What should I do? Walk away from job? How long after can a store contact me in reference to this? Thanks for any direction.
