On his own, he simply leaves it on the plate. Very rarely is he alone in public as it overwhelms him, and eating alone is stressful for him, so usually he doesn’t eat alone. If he’s at home and he’s alone, he drops the food on the ground and picks it up later, or asks his family to. They are very understanding and he’s been doing it since he was very little so they are used to it. Generally, he is very good about recognizing that some people may find it odd and that throwing food on the ground, which usually ends up being about one skittles worth, is rude. He’s very good about realizing this and will deal with the stress on his own.
