1. Watch for establishments that have a "Now Hiring" poster (rare these days) and inquire.
2. Go into any chain establishment, be it a grocery store, or fast food place...etc and ask if you can have an application. Worst case scenario is that they say they're not hiring. (it's dead easy to get accepted into fast food, I recall someone who applied to Taco Bell completely as a joke putting down information on the fields that would have any sane person calling the police, he got the job)
I feel bad for people, especially kids who are trying to get jobs now. Fortunately I secured both of my current jobs before the crash.
Good luck!
