Negotiating an offer, is it too late? after 5 years as a barista

I received an offer as a barista and I think the pay is a little low. The hiring manager was friendly and open. Did it backfire?

If they say no, consider asking for something else, such as a review in six months.

I thanked them and said I was excited but hoped we could talk about the pay. They came back with a bit more.
