I don't think this is really that big of a concern. If you try to negotiate for more pay, I don't think anyone is going to rescind the offer. The worst case is that they won't budge, in which case you can still take it.
If someone is willing to rescind an offer because they are upset that you tried to negotiate, it's probably not someone you want to work with anyway.
