Possible +?

The Assistant Manager of Michael's called me today, they want me to come in on Wednesday and fill out the paperwork for employment. I wanted to tell the lady no because my interview was 4 weeks ago and when I called to find out why they hadn't called me in yet she told me she would call me early the next week but she didn't. Then I ran into the manager and she recognized me and said hi, but still I didn't get a call. I would love to work for Michael's but I just don't think they'll have enough hours for me, even part-time. I said yes though, I'm not sure if I need to wear the uniform though. I should probably call and ask. :/
