My question involves criminal law for the state of: California
Yesterday, I went to a store to return a bag and buy makeup. After returning the bag, I looked for another one. While I was trying on a bag, I had stomachache and wanted to go to the bathroom. Even though there're restrooms inside Macy's, I don't know exactly where they are. However, I know where the restrooms are inside the mall where Macy's located, just a few steps from Macy's. So, I headed to the restroom forgetting that I still had an unpaid bag on my shoulder. Only when I was inside the restroom, did I realize that I had the bag with me. So, after leaving the restroom, I headed back to Macy's to return the bag. I also bought back the one that I returned as I couldn't find any thing else, and the makeup, of course.
That's basically my story. My question is whether there's any chance that I can be convicted of shoplifting. I have had paranoia since then. After leaving the mall, I stopped by H&M on a road right opposite to the mall. I was just looking at the accessories there and left after 5 minutes. On my way to the door, I heard the store's phone hung on the wall ringing, I looked at it and saw "mall security". I was scared that they thought that I shoplifted and were after me. Now, I feel worried most of the day and am in the status of waiting for a notice coming in the mail or a cop showing up at my door.
Thank you so much for your time and advice.
