I am considering doing this too. I am working from home at my main job and I have been doing so much work for them... but not getting paid.
So I walk around the mall on weekends and there are a ZILLION help wanted signs. I just want a relatively easy job for nights and weekends.
Ironically though I want a job I don't have to really jump through hoops for... just hire me if you are really desperate. I don't want to have to interview or dress up nice.
