@eris2cats @pluralistic It absolutely is a thing. I like to try new stuff, so I often order things in restaurants that I'm not sure I'll like (especially from foreign cuisines). On the occasions where I don't like them and leave the bulk of the dish behind, the waiter will often offer to take it off my check. I generally try to tell them that I knew what I was getting into, so if the dish was prepared correctly then there's no reason to take it off. Sometimes they still do anyway. (So now I at least push the food around to make it appear I ate more.)
