I cooked for thousands of people, and truth be told, food allergies aside, if someone says "I don't like X" but "X" is in something that tastes amazing, add X anyway. I've never had someone say "I told you I don't like onions, but I think there are onions in this!".
I've discovered many things I didn't think I actually liked thanks to this.
