Which covers "I didn't order it, but I wanted it," "I ordered it but I didn't want it," "I didn't read the menu and didn't know that came on it;" "I didn't read the menu and didn't know that cost extra;" "I am suddenly allergic to this thing that I didn't bother asking about when I ordered;" "My food tastes like X to me despite there being no Earthly reasons why it should." (Though the last applies just as often to drinks as to food--ie "This Coke tastes too syrupy/too weak/flat to me" despite the rest of the dining room having no problem with it.)
