If I was injured at a fast food store, will I be compensated?

A few days ago, I went to McDonalds to get a soda before my daughter's appointment but went to the restroom first. When I grabbed a piece of toilet paper, the dispenser fell and took a chunk off my nose. I left thinking the injury would be okay. We were late for my daughter's root canal. I called the corporate office and informed them of the hazard, and the manager called. I explained what happened. I told her I wasn't dying or anything but there is a decent sized piece took out of my nose. What should I do now?
