Summer Job

I am debating on getting a job this summer while I am living in Hattiesburg. I already have a waitressing job on the weekends back home but I will be living up here all summer long with nothing to do during the week. So should I get a job or not? If I do, what kind of job should I get? I do not want a demanding type of job where my studies will be hindered. I may just work where I live or possibly at Buckle. Truthfully, I have no idea what I am going to do.
