Should I stay or should I go?

I put in my 2 weeks notice this past monday. I got a new job with better pay and benefits. At the age of 29, this will be my first real job with benefits. But I decided on Monday that I was going to give my employer 2 weeks to be nice to them. They haven't been too bad of employers but one boss we swear is bipolar. When I told the head boss I was quitting, he didn't ask why I was quitting, but proceeded to tell me that giving them enough time in advance when I left the week before for vacation wasn't suffice. I left 2 hours earlier that what I was going to leave at. He griped me out for that. After he was done yelling at me, I went back to my desk and tried to work. I should have just gotten up and left. Anyways, its been a couple days since then and the head boss doesn't even care that I'm here. Doesn't acknowledge me, say hello, nothing. What would make me stay here any longer? Besides being the only designer, but that's their fault for not getting another one to fall back on if something was to happen to me. They have no safety, but I don't want to be here if i'm not getting treated like i should be. Plus next week I'm supposed to be on jury duty for the whole week...so i will be out the next week if i'm selected. What do you all think...should I stay or should I go?
