My 21 month old daughter continues to turn her plate of food upside down, falling either on her tray or on the floor. She also spits her food out when she's decided that she's had enough, maybe after a couple of mouthfulls. Despite us telling her that it is wrong to do so; she persists - and we don't fuss over her by giving her food we think she'll eat as an alternative. As soon as she does either of these we bring it to her attention that it is wrong, give her a chance to eat properly and if she doesn't we move her to the naughty spot. However this doesn't seem to be working and I'd value your suggestions and strategies which may have worked for you.
