Don't write off waiting tables just yet.
If you are an adult, don't look like you slept on the street last night, and have your own teeth, you can do well as a server. Bring the manager a resume and go for it. I'll hire someone in their 40's with no experience with no problem if they have a professional background.
Have the right mindset and you can make great money. Hell, these kids make more than I do and I RUN the joint.
If I was prohibited from doing so, I would probably pick up a couple night waiting tables myself.
Good luck.
