You will almost certainly be considered. I've negotiated my offers up anything from 20% to 50%, which means usually my first counter-offer was higher than that.
I'd never just say yes.
By the time someone has made the decision to make you an offer, they have invested time in you, and will be psychologically invested in their decision - nobody likes "losing out", and so they will look for reasons to meet you. As long as your counter-offer is not ridiculous (and tacking on 30% is not), they will negotiate.
Just don't across as making hard demands, and give reasons even if they're total nonsense. People yield more easily if you give them an excuse to.
The irony is that people also tend to feel they made a better deal if they have to fight for it, even if they end up giving a lot.
