What's the usual protocol when a customer says meat was undercooked?

I went to a mom and pop type of restaurant on Sunday. We ordered some fried chicken wings and the first wing someone tried was bloody. So I told the staff about it and they said they would fry them again. I don't think they actually replaced the chicken wings with a new order. They just refried the same ones. Last night I had food poisoning and was vomiting all night and I'm still weak and achy today. I wonder if there was some kind of contamination with the undercooked chicken still. Is it normal to just recook the same meat or do restaurants usually give you a whole new order in that situation?
