McDonald's has really high turn-over so if you've been there for more than six months you're probably a god to the new people.

Regarding the temps quitting without any notice stuff, it's allowed as far as I know due to the nature of the contracts. Either party can terminate it without any notice, but it makes the temp company look bad if the people they send out start quitting all over the place with no notice. I wouldn't expect an favours after doing something like that.
