So does drinking a bit of water from some unknown bucket or spring. You can feed characters anything you like and they won't resist at all, even poisonous meat, bitter wine etc. In fact, you can feed them as much as you want and they won't feel full. If you don't feed them anything, they won't feel hungry either, despite all that fighting they do. Cooks never cook, they always give you information.
Fishermen never fish either.
No-one needs to eat or drink, apart from those same people always sitting around in the pub. You can always bring the dead back to life by simply using an item if they've died in battle, even if they might have been blown apart by some explosion magic. Unless they die as part of the storyline, in which case nothing can be done to save them. You never hear yourself talking when you talk to other people. You can talk to the same person over and over again, and they'll tell you the same thing over and over again.
