$3 an hour?

Hi I'm a mother of one child. My husband is working and makes roughly $600 every other week. I'm thinking of getting a job so I can have some extra cash on me for little things I need and stuff that I like for my daughter, he buys everything she needs and I need and I just feel like that isn't correct I need to help a little. For example I would my money on stuff for my daughter but not stuff she NEEDS just little things here and there that I like for her and for myself makeup lol. ANYWAYS. I found a job, keep in mind this will be my first job ever it pays $3 an hour plus tips and you get paid every Friday. I know it's not much at all but I heard it's a really easy job and I think it would be great for my first job and from there I can possibly feel ready to get a better paying job. Question - Who has worked somewhere that pays $3 an hour? how much we're your checks? and is it worth it or should I try to find a better paying job? like I said I really just want to work to have extra cash on me.
