Any job shows you can be reliable and a good worker. Its easier to get another job if you already have one . Some money is better than none. Make sure you contact food pantries and your county welfare department, you may qualify for rentl assistance or at least food stamps.  Look at any shelters in your area. You need to have a place to take care of personal hygiene (shower) and keep clean clothes or you wont find or keep any job.  Any food you get free means what money you have can go for other expenses. 

A busboy job may get you a free meal at that restaurant or takeout box with whatever leftovers they have.  Its an important job in a good restaurant because you are in the publics view. It needs to be done quietly and neatly.  Sometimes the waitresses split tips with the busboys.
