should I or should I not...

Well I went to that interveiw today and I have mixed feelings. THe boss told me she was anal and that she wants things her way or the highway. I am a sales person so that means I have to see you the tanning beds. I work on commission so I don't know. I am not sure if I want the job. I mean she said mon, thurs, and friday I would work. Then every other weekend. RIght now I have this bible study that takes up my thursdays and I have two classes on tues and weds. I really want the extra cash but I don't know if I want it this bad.
