Not sure how old your kids are, but when my youngest daughter (5) is wanting to be awkward about something be it food (which she knows presses the right buttons) or getting dressed, going to bed etc I go into TV presenter mode and talk as if she is my co presenter, and say "hello & welcome, today we are going to show you how a princess washes her hair etc" and include the negative bits humourously in the "text" e.g "some princesses may scream their heads off, but we know that isn't really needed" we have a laugh, the task is done and no-one gets stressed. Even though she really enjoys it it hasn't reinforced being awkward so she gets to play the game, as usually she's awkward when tired. She has suggested on the odd occasion that we play the game when she's in a perfectly good mood and baking cakes or something, but it works for us, and stops both of us feeling tense & exhausted! The swimming baths work well before any meal! The Princess who doesn't like onions,spices etc wolfed down a homemade curry, rice & paratha on her return. Then asked for the leftovers for yesterdays lunch.
