I can see it as positive if you sell it properly. Having a job outside of medicine shows that you have other interests and not just trying to do whatever it takes to be a cookie-cutter applicant to get into med school. You explored other careers and options and maybe gained little more insight in terms of why medicine may be a better fit than something else. Also, there are plenty of universal skills that are transferable. For example, if you were in management, leadership, or a teaching position, you may bring a perspective and experience to class that the rest of the class who worked primarily in medicine as EMT's, lab technicians, or scribes may not have.
I may be completely wrong about this, but if I was on the admission committee I would look at your experiences from the standpoint of how it impacted you and how you as a person, given your experiences, will contribute to the overall intellectual diversity of the class.
