Minimum wage positions often require very little technical skills, similiar to the positions listed above. While it's always important to find work as quickly as possible, be careful not to jump (and settle) for a position too quickly. Depending on your background and experience , yes, it may take a few months to land you a great job, but it may be worth it. This is a decision each person will have to individually assess.
The possible negative of taking a non-related minimal paying job too quickly is that when you try and apply for a position back in your field at a intermediate level you may have more problems, then if you'd stuck it out a few months in the beginning.
