I'm too nice

and people I work with take advantage of it. It sucks kind of because any time someone asks me to work for them, I can't say no. So sometimes I'll end up working 6 or 7 days a week because I literally cannot say no. 

Like, on Friday I was supposed to work 5-10 but I ended up staying and closing for a guy that I work with because he asked me to and I couldn't say no, 

and then on saturday we were SO busy, I was supposed to work 12-8, because I always ask to work 12-8 on saturdays cause I love working 12-8. anyway, we were so busy and someone called in, so I ended up staying 12-9.
