lol NB I have one who won't even try treats. She's a suspicious eater but not a picky eater [she's easy to worm, will eat feeds with bute in them and I don't even have to put any molasses in]... I know that doesn't outwardly make much sense but have you ever known a person who will eat things that are absolutely gross, but won't try anything new? She's like that. Her "treat" is a palmful of pellets, because that's all she'll even try. She doesn't know what carrot/apple/etc is, so she won't try it.
With Mum's pony and my gelding, on the other hand, if the human is eating it, it must be food, and therefore they must try it.
