Undoubtedly galley FM. There are very clear procedures for dealing with scenarios such as this, which for obvious reasons I won't detail here. I take everything I hear from our cabin crew with a pinch of salt as you can explain everything to them in clear, monosyllabic terms as many times as you like and they'll still stick to the conclusions they jumped to before they had any facts. The only commercial pressure in these situations is from the cabin crew who've got their eyes on an overtime payment of some sort.
