Some pluses: it gets you out of the house and a paycheck (even if it's a small one). The opportunity to get some nice clothes at a very nice discount.
The customers could end up being very nice as Chico's is a nice store (but not on the level of a Macy's)
You Can keep looking for a job. If after an honest try, this job doesn't work out? You can politely quit.
Is there any kind of job training/computer skill classes or anything else like that available to you through the county or a local community college?
