Hey-
Try tutoring, or if all else fails, get a job that you hate and quit when you go to grad school. I would recommend pizza delivery- you get minimum plus tips and mileage.
With the economy the way it is, I personally don't feel that there is any room to be prideful in making employment decisions. I've worked all the way through my undergrad at low paying jobs, and it only builds character. Just think, if you work at a terrible job now, when you get to grad school, you'll feel incredible about where your life is going.
Good luck,
J
