It sounds to me like they did see you. They likely didn't immediately move on you because they wanted to see if you were going to do anything else, as well as going back and investigating to see if you did anything prior. It is entirely possible they could pull you when you return to work. Understand that being fired is not your only worry, Macy's does prosecute employee theft cases. It may be a hard sell with prosecutors since it will have been a long time since the theft but they can and do still try.
