Just as a word of advice: don't do the patient contact jobs if you only want to bolster your resume. If you'd prefer to work at Chuck E Cheese or in a research lab, or as Mickey Mouse on a Disney Cruise ship (I looked into this one...), do that instead. Patient contact jobs aren't going to make or break your application to podiatry schools. If you aren't socially challenged, your GPA > 2.9, and your MCAT > 20 you will (95% of the time...) get into a podiatry school.
You're (presumably) young! Have fun, and work someplace that you want to work. Don't work as an EMT/Phlebotomist/Receptionist because you think it will help you somehow. If these sound like the jobs you want regardless of your application, then obviously pursue them. If not, then don't.
