I would suggest that whatever training you have done, didn't take or the dog would not be ordering you out of the room. There is more going on here than just the food business. It is very likely that you need to go back and start over with the training to establish what place the dog holds in the household and work up to the food issue after you have worked out who is in charge in the rest of things. It isn't just that he might bite someone who you want to take care of him, he sounds very much as if he might bite you if you don't follow his instructions. If you need him to be cared for please take him to a proper boarding kennel where they are equipped to deal with him and give them proper warnings that he can be dangerous so they manage him with regard to that.
