We never pick it again, it’s unpinned, and if Auto-pick had already put it in an upcoming delivery we swap it for something else. Meals you chose yourself are left alone.
On a past delivery you can tell us why: too spicy, bland, portion size, texture and so on, with a note if you like. That goes straight to the kitchen and helps us improve the menu. If something was wrong with a meal, use Report instead and we’ll get back to you.
