I could see it being Kizaru and then Luffy says "thank you for giving me food Kizaru" and accepting that he sides up with him.
I don't think that Luffy can hold a grudge on Kizaru knowing that his grandpa is a marine and he knows that Kizaru is just doing his job.
It could also be just Caribou or one of those food machines that broke.
