If the place where you work does not offer a living wage DON'T TAKE THE JOB
It's not always that easy to be picky. When I was putting myself through college I couldn't take a day job because of my class schedule. In my area, that left me with minimum wage night jobs or serving jobs at resturaunts that all (every single one out close to 100 sit-down resturaunts in the vicinity) paid $2.13 an hour plus tips. I took my chances and went to work as a server at Chilis and worked there for 4 years. When I started out, I sucked. I had worked at numerous hard labour jobs as a witness doing things such as building scaffolding, laying concrete driveways, drywall, and landscaping, but waiting tables was definitely the most stressfull job I've ever had, even considering my current job. But no one knows that there is actually a lot involved unless they've been there.
Most people seemed to think servers make minimum wage. I figure the only way to change the apropos is for all servers to go on strike for a higher wage, which would get the word out about what the wage really is. But, of course, the majority don't have the time or the funds to subsidize what it'd take to organize such an effort. And it most likely wouldn't work, because the resturaunts would just hire a brand new batch of people that were willing to work for $2.13 plus tips to replace those that were unhappy. So go figure.
